The mechanisms of hemoglobin precipitation into Heinz bodies and hemolytic anemia that characterize congenital Heinz body hemolytic anemia (CHBHA) were studied in patients with the unstable hemoglobins, Köln (beta-98 valine --> methionine) and Hammersmith (beta-42 phenylalanine --> serine). The cysteines in the 93rd position of the beta-chains of CHBHA hemoglobins bound glutathione excessively in mixed disulfide linkage. The resulting diminished "free" GSH within the cell accelerated hexose monophosphate shunt metabolism. The unique precipitability of CHBHA hemoglobins when heated at 50 degrees C could be induced in normal hemoglobin A by artificially blockading its sulfhydryl groups with paramercuribenzoate (PMB). Reflecting the previously reported excessive flux of hemes from hemoglobin Köln, the expected heme/globin ratio in this hemoglobin was reduced by 30%. The further increment in heme loss that occurs with heat (50 degrees C) underlies the unique heat precipitability of CHBHA hemoglobins; it was retarded if detachment of heme was inhibited by cyanide or carbon monoxide.Heinz bodies were attached to red cell membrane thiol groups presumably through mixed disulfide bonds, being released by mercaptoethanol. Binding of hemoglobin Köln-(59)Fe to red cell ghosts, which was markedly enhanced when Heinz bodies were generated at 50 degrees C, was inhibited if membrane thiols were preblockaded by PMB. The depletion of membrane thiols by their reaction with Heinz bodies rendered CHBHA red cells hypersusceptible to membrane sulfhydryl inhibitors, as manifested by inordinate cation leakage, osmotic fragility, and autohemolysis. We conclude that both cellular and membrane thiols bind beta-93 sulfhydryls of CHBHA hemoglobins as mixed disulfides. Concomitantly, heme avidity to beta-92 lessens, suggesting that degradation of the resulting excessively freed heme may produce the pigmented dipyrroluria of this syndrome. Heinz bodies, reflecting the heightend precipitability of heme-deficient globin, attach to, thereby depleting, membrane sulfhydryl groups. This, as shown previously, could underlie the hemolytic anemia of this syndrome by causing membrane hyperpermeability, premature splenic entrapment, and ultimately osmotic destruction of red blood cells.

In western Canada, dugouts are the primary source of water for beef cattle during the summer months. Over time, drought conditions and/or direct access by grazing animals have a negative effect on water constituents and overall water quality. A study was conducted to determine the effects of improvements in water quality on cattle performance. The effect of pasture water quality on weight gain of beef cattle was assessed with 44 Hereford yearling steers over 5 years and 40 Angus cow–calf pairs over 3 years. From 1999 to 2003, cattle were allocated to 1 of 4 treatments, which comprised untreated dugout water pumped to a trough, aerated water pumped to a trough, and coagulated and chlorinated water pumped to a trough, all compared with direct access by livestock to the water source. Data were collected on livestock weight gains, water consumption, fecal parasites, environmental conditions, water chemistry, biological constituents, and forage production and quality. Water treatment by aeration or coagulation tended to improve steer weight gains (P < 0.05) over untreated water from a dugout in 3 of 5 years. Daily weight gains tended to be improved slightly by simply pumping water to a trough without treatment. Water aerated and pumped to a trough in early summer tended to produce greater (P < 0.05) weight gains in calves than those drinking directly from the dugout. The effect of treatment on improving cattle weight gains appeared to be related to improved water palatability, which increased water and feed consumption. Water chemistry and biological constituents analysed did not identify significant differences among treatments. These results suggest that improving water quality with aeration and pumping to a trough will improve weight gain 9–10% over a 90-day grazing period in most years.

Physical illness is a life experience which challenges an individual's sense of control and thus represents a potential threat to mental health. For children, a serious illness threatens not only their sense of physical and psychological well-being but also threatens the psychological well-being of their family. In this study, severely ill patients (n = 15) and a member of their family (n = 15) were interviewed. The patients, who ranged in age from 12 to 21 years, were being treated for metastatic solid tumors or lymphoma that failed to respond to conventional therapeutic regimens. Correlates of control for the patients and family members, the relationship between control and developmental stage of the patients, and the difference between levels of control in patients and family member were examined. The findings are discussed in relation to development and their implications for medical management.

This investigation reports on follow-up information received from past participants of a school-based social learning program designed for problem adolescents. The follow-up occurred approximately five years after the students' participation in the program. The attitudes and performance of 15 of the original 24 adolescents were assessed on a range of self-report measures, incorporating variables such as their employment and educational status, evaluation of program participation, involvement in leisure-time and community activities, relationships with family and friends, and anticipated aversive consequences of engaging in delinquent acts. Issues of importance to the execution of follow-up studies are reviewed. Data resulting from this pilot study fail to conclusively demonstrate the long-term merits of the behavioral program with this population.

BACKGROUND: Provision of emergency medical services (EMS) in the rural United States presents a unique challenge. While rural and urban EMS outcomes have been compared, differing urban-rural population characteristics and roles for rural ambulance teams can confound such comparisons. METHODS: A year-long study of the prehospital EMS was conducted in rural Richardson County, Nebraska. Data were collected on the age, sex, and race of patients, response time, transport distance, medical problems encountered, and treatment rendered enroute. These data compared with those from an urban Lancaster County comparison group and statistical data from the Nebraska State Health Department. RESULTS: In the rural county, 70 percent of calls involved the elderly, whereas 38 percent of the urban calls and 36 percent of the Nebraska State calls involved the elderly. The rural ambulance service was more likely to provide for routine transfers, to involve patients with fractures and cardiorespiratory and neurologic problems, and twice as likely to result in hospital admission than was the urban ambulance service. The frequency with which advanced life support measures were applied in the rural area was similar to that in the urban area. The rural area response times were equivalent to the urban area response times after the rural area long-distance transfers were excluded. The location of service in the rural area was more likely to be the hospital or nursing home, whereas the urban location was more likely to be a home, on a highway, or in a public setting. CONCLUSIONS: Prehospital EMS in this rural location involved a predominantly elderly population with a large number of routine transfers linking the nursing home and community hospital. Further comparisons of rural and urban EMS outcomes should account for possible differences in type and severity of illness and type and location of service.

CONTEXT: The pituitary gland is key for childhood growth, puberty, and metabolism. Pituitary dysfunction is associated with a spectrum of phenotypes, from mild to severe. Congenital hypopituitarism (CH) is the most commonly reported pediatric endocrine dysfunction, with an incidence of 1:4000, yet low rates of genetic diagnosis have been reported. OBJECTIVE: We aimed to unveil the genetic etiology of CH in a large cohort of patients from Argentina. METHODS: We performed whole exome sequencing of 137 unrelated cases of CH, the largest cohort examined with this method to date. RESULTS: Of the 137 cases, 19.1% and 16% carried pathogenic or likely pathogenic variants in known and new genes, respectively, while 28.2% carried variants of uncertain significance. This high yield was achieved through the integration of broad gene panels (genes described in animal models and/or other disorders), an unbiased candidate gene screen with a new bioinformatics pipeline (including genes with high loss-of-function intolerance), and analysis of copy number variants. Three novel findings emerged. First, the most prevalent affected gene encodes the cell adhesion factor ROBO1. Affected children had a spectrum of phenotypes, consistent with a role beyond pituitary stalk interruption syndrome. Second, we found that CHD7 mutations also produce a phenotypic spectrum, not always associated with full CHARGE syndrome. Third, we add new evidence of pathogenicity in the genes PIBF1 and TBC1D32, and report 13 novel candidate genes associated with CH (eg, PTPN6, ARID5B). CONCLUSION: Overall, these results provide an unprecedented insight into the diverse genetic etiology of hypopituitarism.

Condensed tannins in sainfoin (Onobrychis viciifolia) improve forage digestion and reduce the risk of ruminant bloat caused by grazing alfalfa (Medicago sativa). The objectives of this study were to evaluate the forage dry matter yield (DMY) and persistence of newer sainfoin cultivars in mixtures with alfalfa, and to determine the impact of harvest frequency on the persistence of sainfoin. Sainfoin cultivars ‘AAC Mountainview’, ‘AAC Glenview’, ‘Delaney’, ‘Shoshone’, and six experimental populations were compared with ‘Nova’ and ‘Melrose’ at Lanigan, SK, from 2016 to 2018. Field plots were seeded in either monocultures of sainfoin at 33 kg·ha −1 or sainfoin–‘AC Grazeland’ alfalfa mixtures at 16:9 kg·ha −1 in alternate rows. Forage DMY was greater (P = 0.001) in mixtures than in sainfoin monocultures in all harvests. The proportion of sainfoin in mixtures at Cut 1 declined from 4.1% to 1.3% of total DMY from 2016 to 2018, and 19.0% to 4.8% in Cut 2, which was less than the recommended level to eliminate ruminant bloat risk. A second field trial was established in 2017 to compare responses of ‘AAC Mountainview’, ‘Nova’, and ‘Shoshone’ sainfoin under one-, two- or three-harvest frequencies in 2018 and 2019. The increase of harvest frequency did not reduce sainfoin stand (%). Stand percentage of ‘AAC Mountainview’ (91%) was greater (P = 0.01) than ‘Nova’ sainfoin (62%). Further agronomic studies focusing on weed control in sainfoin stands and the optimum seeding ratios of sainfoin–alfalfa within the Parkland region of Saskatchewan are needed.

São diversificadas as recomendações referentes à temperatura (T°) e umidade relativa do ar (UR) no armazenamento de materiais esterilizados em Centrais de Material e Esterilização (CME), sem que essas recomendações estejam embasadas em referenciais teóricos ou experimentos. A prática mostra dificuldades em controlar esses parâmetros, suscitando dúvidas quanto ao risco para a manutenção da esterilidade dos materiais. Este artigo propôs, por meio de uma revisão bibliográfica integrativa, identificar e analisar as recomendações referentes à T° e UR indicadas para o setor de guarda dos materiais na CME. Não foi encontrada literatura que justifique tais recomendações. Foram incluídas sete publicações que analisaram as variáveis T° e UR da área de armazenagem como fatores que podem afetar a manutenção do material esterilizado, e apresentaram resultados contraditórios quanto à interferência desses fatores na manutenção da esterilidade dos materiais.

Abstract Lehman Caves is an extensively decorated high desert cave that represents one of the main tourist attractions in Great Basin National Park, Nevada. Although traditionally considered a water table cave, recent studies identified abundant speleogenetic features consistent with a hypogenic and, potentially, sulfuric acid origin. Here, we characterized white mineral deposits in the Gypsum Annex (GA) passage to determine whether these secondary deposits represent biogenic minerals formed during sulfuric acid corrosion and explored microbial communities associated with these and other mineral deposits throughout the cave. Powder X‐ray diffraction (pXRD), scanning electron microscopy with electron dispersive spectroscopy (SEM‐EDS), and electron microprobe analyses (EPMA) showed that, while most white mineral deposits from the GA contain gypsum, they also contain abundant calcite, silica, and other phases. Gypsum and carbonate‐associated sulfate isotopic values of these deposits are variable, with δ 34 S V‐CDT between +9.7‰ and +26.1‰, and do not reflect depleted values typically associated with replacement gypsum formed during sulfuric acid speleogenesis. Petrographic observations show that the sulfates likely co‐precipitated with carbonate and SiO 2 phases. Taken together, these data suggest that the deposits resulted from later‐stage meteoric events and not during an initial episode of sulfuric acid speleogenesis. Most sedimentary and mineral deposits in Lehman Caves have very low microbial biomass, with the exception of select areas along the main tour route that have been impacted by tourist traffic. High‐throughput 16S rRNA gene amplicon sequencing showed that microbial communities in GA sediments are distinct from those in other parts of the cave. The microbial communities that inhabit these oligotrophic secondary mineral deposits include OTUs related to known ammonia‐oxidizing Nitrosococcales and Thaumarchaeota, as well as common soil taxa such as Acidobacteriota and Proteobacteria. This study reveals microbial and mineralogical diversity in a previously understudied cave and expands our understanding of the geomicrobiology of desert hypogene cave systems.

OBJECTIVE: Potential process differences between hospital and community-based endoscopy for Barrett's oesophagus have not been examined. We aimed at comparing adherence to guidelines and neoplasia detection rates in medical centres (MC) and community practices (CP). DESIGN: Retrospective analysis. SETTING: All histologically confirmed Barrett cases seen over a 3-year period in six MC and 19 CP covering a third of all upper gastrointestinal endoscopies (n = 126,000) performed annually in Berlin, Germany. MAIN OUTCOME MEASURE: Rate of relevant neoplasia (high-grade intraepithelial neoplasia or more) in both settings in relation to adherence to standards. RESULTS: Of 1317 Barrett cases, 66% were seen in CP. CP patients had a shorter mean Barrett length (2.6 cm vs. 3.8 cm; P < 0.001) with fewer biopsies taken during an examination (2.5 vs. 4.1 for Barrett length <or=2 cm; P < 0.001). CPs also provided fewer complete esophagogastroduodenoscopy documentation (25.1% vs. 57.8%, P < 0.001). Neoplasias were found more commonly in MCs compared to CPs (9.2% vs. 0.8%; P < 0.001). However, on exclusion of all referred patients with known neoplasia (65%) or those examined for other reasons (27.5%), the detection rate at MCs decreased to 1.3%, not different from the one seen at CPs (0.8%, P = 0.43). Only 13% were found during surveillance, but 57% were diagnosed at an early stage. CONCLUSIONS: Referral bias and not better adherence to guidelines could explain the higher neoplasia prevalence in Barrett's oesophagus at hospital centres. Despite a generally poor adherence to guidelines, most neoplasias found were at an early and potentially curable stage.

We provide a comprehensive overview of historic chloride concentrations in the groundwater of the Twin Cities metropolitan area (TCMA) in Minnesota, in order to define the extent of chloride contamination, due primarily to the seasonal application of deicing salt to roadways. Data collected from 1278 wells between 1965 and 2020 are representative of the major aquifers underlying the TCMA and establish a regional natural background chloride concentration of less than 10 mg/L. However, 55% of all measurements (1616 of 2943) are above 10 mg/L, with the highest concentrations found within the uppermost Quaternary aquifers. Chloride concentrations in underlying bedrock aquifers are negatively correlated with the thickness and clay composition of overlying materials. Most chloride measurements (92%) remain below chronic exposure limits set by state and federal authorities. Historical trends indicate that, if the current imbalance between chloride inputs and outflows persists, chloride concentrations in TCMA aquifers will surpass regulatory thresholds by midcentury as surface waters and Quaternary aquifer waters migrate into underlying bedrock aquifers. Most wells in this study are monitored annually, making it impossible to detect important sub-annual fluctuations of chloride concentration that can exceed 40%.

Recent experimental and clinical investigations have determined and established the following important facts: The human ovary has an internal secretion. This internal secretion dominates menstruation and maintains pregnancy during the early months. Corpus luteum is the structure chiefly concerned and the probable source of the internal secretion. The corpus luteum of pregnancy is more stable than that of ovulation. Corpus luteum has a selective action on the endometrium and prepares the uterine mucosa for the reception of the ovum. The acme of development of corpus luteum is synchronous with the onset of menstruation. There is a distinct relationship between corpus luteum and the other internal secretory structures of the body. Removal of all lutean tissue is followed by cessation of the menstrual flow. Animal corpus luteum, when administered

ABSTRACT A discriminative avoidance conditioning technique was used to study urinary excretion of selected adrenal hormones in response to a stimulus which had acquired conditioned noxious properties through association with availability of punishment. A four day test procedure was employed: (1) to habituate subjects to the test environment; (2) obtain control data; (3) condition subjects; and (4) test reactions to the conditioned noxious stimulus. Urine samples were taken at two‐hour intervals preceding and following each of the four trials, and were analyzed for epinephrine, norepinephrine, total 17‐hydroxycorticosteroids, and other urinary constituents. These results were correlated with results obtained from monitoring of heart rate, skin resistance, blood pressure, and three measures of panel monitoring performance. Data analyses revealed significant changes from control levels during the test period for each of the principal measures described above and some specification of life systems interrelationships through correlation and factor analyses. Factors were identified which related to behavioral efficiency, psychological effort, fluid transport regulation, cardiovascular‐adrenal, and specific epinephrine and norepinephrine factors.

BACKGROUND: High altitude pilgrims typically ascend rapidly, are not well prepared for the austere environment and tend to have multiple co-morbidities. Here, we list the trend of altitude and other illnesses who visited Humla district hospital (2,950 meters) following very rapid ascent to Kailash Mansarovar (4,500 meters). METHODS: A prospective study was conducted among 55 patients at the Humla District Hospital from September 2019 - August 2022. Patients who fell ill during pilgrimage and brought to the hospital were included. The patients were assessed with medical history and clinical examination. Lake Louise Score Acute Mountain Sickness Score (2018) was used for the diagnosis of Acute Mountain Sickness. RESULTS: A total of 56 evacuees visited the hospital which included 55 patients and 1 brought dead. The mean age was 50.63 ± 10.91 years. Sixteen patients (29.1%) developed symptoms within 24 hours and 15 patients (27.3%) within 48 hours of ascent. Headache 42 (76.4%) was the most common complain. Mild acute mountain sickness (30.9%; 17 patients) was the most common altitude related illness while 14 patients (25.4%) were diagnosed with non-altitude related illnesses. Twelve patients (21.8%) had co-morbidities like hypertension and diabetes mellitus. CONCLUSIONS: In the rapidly ascending pilgrims, majority of travelers requiring medical attention are suffering from some form of altitude illnesses. Hence, proper planning and public awareness about slow and gradual ascent profile is necessary to make the travel safer.

Zero-till seed drills are readily available for crop seeding in the prairie region of western Canada but have not been evaluated for sod-seeding in perennial forage. Sod-seeding a legume, such as alfalfa (Medicago sativa L.), into the existing perennial grass vegetation improves forage yield and quality for ruminant livestock grazing and production. Suppression of the existing vegetation with herbicide has been reported to increase alfalfa seedling establishment. We evaluated six commercially available zero-till seed drill openers by sod-seeding alfalfa into a crested wheatgrass [Agropyron cristatum (L.) Gaertn.] pasture with or without glyphosate suppression of the existing vegetation in Lanigan Saskatchewan. Alfalfa seedling establishment (52.2 vs. 21.9 seedlings m −1 ± 6.8), alfalfa composition (42.5% vs. 0.2% ± 8.6), and alfalfa yield (1105 kg·ha −1 vs. 12 kg·ha −1 ± 206) in 2011 were increased by the application of herbicide. Seed drill openers performed similarly for all three variables. Nine years later, in June 2020, there was greater alfalfa composition (13.3% vs. 0% ± 2.3) and forage yield (1325 vs. 957 kg·ha −1 ± 127) in the sod-seeded plots than in the unseeded controls but the alfalfa plant cover, alfalfa composition, alfalfa yield and forage yield were similar among seed drill openers. There was also no difference in these variables due to herbicide application nine years prior. Livestock producers can utilize currently available zero-till seeding equipment for sod-seeding alfalfa to rejuvenate grass pastures in the thin Black soil zone of western Canada with the expectation of persistence of alfalfa for nine years.

La desaparición forzada de personas es uno de los fenómenos más extendidos a nivel mundial y que plantea particulares desafíos para diferentes áreas del Derecho internacional contemporáneo. El autor analiza su criminalización internacional, ya sea como crímenes de lesa humanidad o crímenes de guerra, así como la configuración de sus ámbitos material, personal –sujetos perpetradores– y temporal. Por otro lado, se examinan las obligaciones de sanción, no amnistía y reparación a las víctimas; obligaciones que tienen los Estados frente a este crimen que constituye una violación seria del núcleo duro de derechos humanos y del Derecho internacional humanitario. El análisis de los tratados y jurisprudencia internacional pertinentes son las fuentes principales de esta investigación.
