Regional Variations and Adaptive Morphology of Apis cerana Forelegs Across India

This study investigated the foreleg morphometry of Apis cerana across 16 diverse locations in India, spanning the northern, southern, and northeastern regions, to explore regional adaptations and environmental influences. The foreleg measurements were analyzed for five key segments: The coxa, trochanter, femur, tibia, and tarsus. Significant regional differences were observed, with northern populations exhibiting larger dimensions, southern populations showing smaller forelegs, and northeastern populations showing intermediate measurements. These variations are likely linked to the distinct climatic conditions and flora in each region, suggesting adaptive responses to environmental pressures. The tibia showed consistent dimensions across all regions, indicating its evolutionary conservation for basic leg functions, whereas the coxa and trochanter exhibited higher variation, reflecting fine-tuned adaptations to local ecological demands. This study provides valuable insights into the morphological diversity and functional adaptations of Apis cerana, contributing to our understanding of how environmental factors shape honeybee morphology.

Phylogeography and population genetics of the endemic Italian water voles, Arvicola italicus

The genus Arvicola has a wide palearctic distribution and present two ecological forms – terrestrial and aquatic – characterizing the genus. In Europe two species are present: the most widespread, A. amphibius and A. italicus, endemic to Italy. The aim of the study was to describe the genetic structure and variability in A. italicus and the genetic identity of populations in northeast Italy, an area of biogeographic importance as contact zone for small mammal species.Thirty-six Italian water voles, displaced in population from south to north of Italy, were analyzed by two mitochondrial markers and 8 autosomal microsatellite loci. The phylogenetic analysis on the genus confirmed the presence of major groups mostly corresponding to the species and clades already described. About the Italian specimens, the individuals from one population in northeastern Italy resulted included in A. amphibius revealing the presence of this species in Italy and, in consequence, the possible presence of a putative contact zone between A. italicus and A. amphibius in the northeast. The phylogeny includes a second population from northeast Italy within A. amphibius, but in basal position and with a low support. The values of divergence of this lineage from A. italicus and A. amphibius lie on the threshold between intraspecific and interspecific divergence. Conversely, microsatellite data support a clear distinction between A. amphibius and A. italicus and includes the ambiguous mitochondrial lineage in this latter species. Furthermore, this northeastern population shows evidence of admixture of nuclear loci with the southcentral A. italicus populations, supporting the attribution of these specimens to A. italicus. This pattern could suggest that A. italicus in northeast Italy retained an ancestral haplotype and undergone a long period of isolation respect to the southern populations, without genetic exchange until recent times. Within A. italicus, the admixture shows northern population as the most differentiated showing limited evidence of admixture with the most diverse southcentral. The intraspecific diversity decreases from south to north as expected for an endemic small mammal in Italy. Finally, the low genetic diversity observed in the northern population can be challenging for a species as Arvicola living in fragmented habitats and susceptible to habitat loss; consequently, became important identifying suitable conservation measures for this barely known endemic small mammal.

Mitochondrial Genetic Diversity and Historical Population Dynamics of the Bank Vole $Clethrionomys$ $glareolus$ in Northern Anatolia: Insights from $Cytb$ and $COI$ Gene Sequences

This study presents a genetic analysis of $Clethrionomys$ $glareolus$ populations across northern Anatolia, utilizing mitochondrial $Cytb$ and $COI$ gene sequences. Phylogenetic analysis identified two distinct Turkish clades, Clade 1 and Clade 2. Neutrality tests and mismatch distribution analyses indicate a recent population expansion following a genetic bottleneck associated with Pleistocene climatic changes. Interestingly, bank voles from Uludağ in Bursa Province of northwestern Anatolia exhibited a closer phylogenetic relationship with northeastern populations than with other northwestern populations, suggesting complex historical population dynamics, possibly involving a population replacement in northern Anatolia and relic survival in Uludağ. The geographic boundaries between the clades did not align closely with main rivers, suggesting that these geographic features did not act as strong long-term barriers to gene flow among bank vole populations. Our mtDNA study lays the foundation for future research to evaluate these scenarios using phylogeographic patterns of genome-wide diversity for a comprehensive understanding of the complex evolutionary history of bank voles in Türkiye.

Genetic analysis of village pear (Pyrus communis L.) cultivar populations in northeastern Türkiye

AbstractPear (Pyrus communis L.) stands out as a prominent fruit species in temperate regions worldwide. The Çoruh River basin, nestled in the lower Caucasus in Türkiye, serves as a valuable repository of pear germplasm. To elucidate the genetic structure of pear populations in this region, 84 village pear cultivar genotypes (land races) from six villages, sample garden collections (SCC), and wild Panta root stock populations were analysed using eleven microsatellite markers. Genetic diversity and structure analyses indicated that village pear cultivar populations exhibit substantial genetic diversity and admixture. This diversity is attributed to local farming practices such as phenotypic selection and widespread dispersal of clonal materials. The genetic structure analysis, combined with the identification of private alleles, indicates that the pear genetic resources in the Çoruh river basin likely has originated from two gene pool sources, specifically the Meydancık and Camili village pear traditional cultivar populations. The Camili village pear cultivar population as a new in situ genetic reserve site has been proposed. Despite the existence an ex situ conservation site, the study suggests inadequateness of SCC as an ex situ site in capturing the full extent of genetic diversity of village pear cultivar genetic resources. Thus, enriching the genetic diversity in the SCC ex situ site is essential for effective pear genetic resource conservation in the Çoruh river basin. These findings contribute valuable insights for the development of targeted conservation strategies, ensuring the preservation of pear genetic resources in this region.

Radiological and Anthropometrical Analysis of the Hip Joint Using Computed Tomography Scan in North Indian Population

Abstract Background: Anthropometric research on the hip joint has significant clinical implications, including (1) implant design and (2) avoiding implant mismatch complications, such as aseptic loosening and incorrect load distribution, which are mainly unknown in North India. The aim of this research is to ascertain the anatomical differences in the normal hip joint across individuals in North India and to statistically compare the results with global data. Materials and Methods: We used one hip topogram and one axial segment of the femoral head to analyze 100 people (35 females and 65 males) with normal hips between the ages of 20 and 65. In both sexes and on both sides, we determined the means of the following measurements: femoral head diameter (HD), femoral neck width (NW), femoral neck length, acetabular angle of sharp, femoral version, horizontal offset, acetabular version, and vertical offset. Results: The following are the mean parameters that were observed: (a) neck shaft angle (NSA) - 128.93°, (b) femoral HD = 4.29 cm, (c) femoral NW = 2.97 cm, (d) femoral neck length = 3.61 cm, (e) Acetabular angle of Sharp - 33.01°, (f) Acetabular version = 20.44°, (g) femoral Version = 21.57°, (h) horizontal offset = 3.62 cm, and (i) Vertical offset = 4.43 cm. Conclusion: The NSA and acetabular angle of sharp were 5°–6° more when compared to the western population while horizontal and vertical offset is comparatively less than Western population and in the Indian NSA was higher for North Eastern population than the North Indian population. The residual parameters were comparable to those found in Western literature.

Surveys on Baylisascaris procyonis in two of the three French wild raccoon populations

Human infection by Baylisascaris procyonis can result in larva migrans syndromes, which can cause severe neurological sequelae and fatal cases. The raccoon serves as the definitive host of the nematode, harboring adult worms in its intestine and excreting millions of eggs into the environment via its feces. Transmission to paratenic hosts (such as rodents, birds and rabbits) or to humans occurs by accidental ingestion of eggs. The occurrence of B. procyonis in wild raccoons has been reported in several Western European countries. In France, raccoons have currently established three separate and expanding populations as a result of at least three independent introductions. Until now the presence of B. procyonis in these French raccoon populations has not been investigated. Between 2011 and 2021, 300 raccoons were collected from both the south-western and north-eastern populations. The core parts of the south-western and north-eastern French raccoon populations were free of B. procyonis. However, three worms (molecularly confirmed) were detected in a young raccoon found at the edge of the north-eastern French raccoon population, close to the Belgian and Luxemburg borders. Population genetic structure analysis, genetic exclusion tests and factorial correspondence analysis all confirmed that the infected raccoon originated from the local genetic population, while the same three approaches showed that the worms were genetically distinct from the two nearest known populations in Germany and the Netherlands. The detection of an infected raccoon sampled east of the northeastern population raises strong questions about the routes of introduction of the roundworms. Further studies are required to test wild raccoons for the presence of B. procyonis in the area of the index case and further east towards the border with Germany.

Temporal trends and spatial and spatiotemporal distribution of schistosomiasis mansoni in northeast Brazil between 2005 and 2016.

Schistosoma mansoni is a parasitic disease of great magnitude for Brazilian public health. We aimed to analyse the temporal trend and spatial and spatiotemporal distribution of positivity rates for schistosomiasis mansoni in northeast Brazil. This is a descriptive study with an ecological approach, carried out between 2005 and 2016. We calculated the positivity rate for the disease and then performed a segmented trend analysis (Joinpoint). For spatial analysis, we smoothed the positivity rates using the local empirical Bayesian method. We checked for spatial autocorrelation using Moran's global and local. Subsequently, we performed Kulldorff's space time sweep analysis. In the period under review, 7 745 650 tests were performed in the northeast, of which 577 793 were positive for Schistosoma mansoni. In the historical series of positivities, it is noted that the highest rates were in Sergipe, Alagoas and Pernambuco. The states of Alagoas and Sergipe showed higher positivity in relation to the average positivity of the northeast and of Brazil. The spatial analysis maps identify clusters of high risk of schistosomiasis cases, mainly in coastal municipalities. There was also stability in positivity rates in some states and the maintenance of endemic areas. Thus effective public health policies are needed in health education in order to reduce schistosomiasis positivity and improve the health conditions of the northeastern population.

Association of PCSK-9 with the Biomarkers of Type-2 Diabetes and its Complications in the Indian Population: a Pilot Study.

Proprotein convertase subtilisin/kexin type-9 (PCSK-9) is a serine protease with profound effects on plasma LDL-C, the major risk factor for cardiovascular diseases (CVDs). However, plasma PCSK-9 level and its association with the biomarkers of CVDs, diabetes, and associated complications have not yet been reported in the northeastern population of India. Of the total cohort (n = 233), we analyzed healthy controls (HC; n = 50), freshly diagnosed type-2-diabetes mellitus (T2DM-FD; n = 46), T2DM treated (T2DM-T; n = 49), diabetic nephropathy (T2DM-N; n = 43), and diabetic dyslipidemia (T2DM-DL; n = 45) subjects. Plasma PCSK-9 and other biological determinants associated with T2DM, CVD, and nephrotic dysfunction were assessed. The level of plasma PCSK-9 in HC, T2DM-FD, T2DM-T, T2DM-N, and T2DM-DL groups was found to be 184.1 ± 13.83, 183.1 ± 24.4.3, 241.8 ± 75.42, 403.7 ± 85.94, and 641.3 ± 135.5 ng/mL, respectively, indicating its role in the severity of the here-mentioned complications. Moreover, plasma PCSK-9 levels further showed a significant correlation with the biomarkers of hyperglycemia, particularly HbA1c, as well as LDL-C in T2DM-FD, T2DM-N, and T2DM-DL subjects of the Indian population, while moderate association in T2DM-T subjects. Our first-of-its-kind clinical study aiming to quantify the circulatory PCSK-9 level in the Indian population concluded that elevated PCSK-9 was significantly associated with the severity of diabetes and associated complications. Moreover, such elevation in PCSK-9 might be attributed to the lipid- and glucoselowering medication-induced SREBP-2-dependent mechanisms. Since our conclusion is based on a pilot study, further cohort studies in larger populations of India are required to get a generalization regarding the role of PCSK-9 in DM and associated complications.

Thermal histories reveal spatiotemporal distribution and population overlapping of Sepioteuthis lessoniana

Abstract Thermal histories describe ambient temperature experienced by cephalopod species from birth to death, reflecting their habitats and distributions. Thermal histories were reconstructed by analyzing ontogenetic oxygen isotopes (δ18O values) in statoliths of adult Sepioteuthis lessoniana collected from northeastern and southwestern Taiwan between 2017 and 2019. The probabilities of occurrence associated with thermal histories in the two populations were modeled using a spatial interpolation approach, ordinary kriging method. The northeastern population exhibited larger ontogenetic variations in experienced temperature (ranging from 9.1 to 10.4°C) than did the southwestern population (ranging from 4.3°C to 6.8°C). The two geographical populations exhibited distinct ontogenetic movement patterns and distribution. The southwestern population demonstrated wide dispersal influenced by seasonal wind directions and tended to remain in 20°C isotherm areas around the Penghu Islands for maturing and spawning. At the seasonal cohort level, the northeastern population exhibited a southward shift during the 2-year study period as a result of the El Niño event. The distribution of the two geographical populations overlapped in the adult stage primarily in the northern Taiwan Strait, supporting an assumption of population connection in Taiwan. This study revealed the thermal histories of S. lessoniana, providing insights into the field observation of distribution patterns and the progress in relating population dynamics to environmental variability, which are essential for the sustainable management of squid fisheries.

The Strabismus Prevalence in a Random Sample of Iran's Northeastern Population

Purpose: To investigate prevalence of strabismus and related factors in Mashhad, Iran. Study Design: Cross sectional study. Place and Duration of Study: Khatam-al-Anbia Hospital, affiliated with Mashhad University of Medical Sciences. Methods: Using multistage cluster sampling, participants were selected. All participants underwent detailed ocular examinations. A unilateral cover test was performed with the prism bar to achieve binocular alignment. Deviation magnitude was determined by considering the best refractive correction. Fixation targets were chosen as single letters one line above the best-corrected visual acuity on the distance and near chart. Results: This study included 5054 participants with a mean age of 35.35 ± 19.4 years. Strabismus was detected in 110 participants (2.17%) including 26 (0.51%) with esodeviation, 74 (1.46%) with exodeviation, and 10 (0.19%) with vertical deviation. The prevalence rates for strabismus, exotropia and esotropia were 2.38%, 1.64%, and 0.56% in females and 2.00%, 1.31%, and 0.51% in males respectively. The results did not indicate a significant gender difference in terms of strabismus prevalence (p>0.05). Among the deviated eyes, there were 25.5% with hyperopia, 39.1% with myopia, and 35.5% with emmetropia. Anisometropia and amblyopia rates were 2.79% and 2.55%, respectively. The results did not reveal a significant correlation between strabismus prevalence, exotropia, and esotropia and age (p=0.56). The familial strabismus prevalence was 5.45%. Conclusion: Exotropia was more prevalent form of strabismus. Myopia was the dominant refractive error associated with deviated eyes. Tropia showed no age-related association.

Evidence of differentiation and population structure in Charolais cattle of Mexico.

Charolais is one of the most important beef cattle breeds in the world. In Mexico, it was introduced almost a century ago, and it has been suggested that particular breeding management and genetic material origin have caused a process of divergence among the current population. By a high-density SNP array genome-wide analysis, this study aimed to assess the proposed differentiation and population structure of local populations by genetic distances and structure approaches, and a European Charolais sample was included as a reference population. The differentiation statistics indicated that local populations exhibit moderate divergence, confirming a significant differentiation process between northeastern and northwestern Charolais populations (Fst≥ 0.043, D≥ 0.031). These results were strongly supported by PCA and structure analysis. Genetic isolation and low genetic flow between populations and divergent origins of introduced genetic material (i.e., semen) are likely the main drivers of the outcomes. Some implications are discussed.

Multiple piroplasm parasites (Apicomplexa: Piroplasmida) in northeastern populations of the invasive Asian longhorned tick, Haemaphysalis longicornis Neumann (Ixodida: Ixodidae), in the United States.

Piroplasms, which include the agents of cattle fever and human and dog babesiosis, are a diverse group of blood parasites of significant veterinary and medical importance. The invasive Asian longhorned tick, Haemaphysalis longicornis, is a known vector of piroplasms in its native range in East Asia and invasive range in Australasia. In the USA, H. longicornis has been associated with Theileria orientalis Ikeda outbreaks that caused cattle mortality. To survey invasive populations of H. longicornis for a broad range of piroplasms, 667 questing H. longicornis collected in 2021 from 3 sites in New Jersey, USA, were tested with generalist piroplasm primers targeting the 18S small subunit rRNA (395–515 bp, depending on species) and the cytochrome b oxidase loci (1009 bp). Sequences matching Theileria cervi type F (1 adult, 5 nymphs), an unidentified Theileria species (in 1 nymph), an undescribed Babesia sensu stricto (‘true’ Babesia, 2 adults, 2 nymphs), a Babesia sp. Coco (also a ‘true Babesia’, 1 adult, 1 nymph), as well as Babesia microti S837 (1 adult, 4 nymphs) were recovered. Babesia microti S837 is closely related to the human pathogen B. microti US-type. Additionally, a 132 bp sequence matching the cytochrome b locus of deer, Odocoileus virginanus, was obtained from 2 partially engorged H. longicornis. The diverse assemblage of piroplasms now associated with H. longicornis in the USA spans 3 clades in the piroplasm phylogeny and raises concerns of transmission amplification of veterinary pathogens as well as spillover of pathogens from wildlife to humans.

Historical diversification of Pseudonympha Wallengren, 1857 (Lepidoptera: Nymphalidae: Satyrinae)

ABSTRACT The butterfly genus Pseudonympha and several related genera are endemic to southern Africa. Although many of the species are montane, some inhabit the arid interior of South Africa, offering an opportunity to study the palaeobiogeography of this biome. Morphological data (for all species of Pseudonympha and allied African and Asian genera) and molecular data (WG and COI genes for nine of the 15 species of Pseudonympha and all of the southern African endemic genera of Ypthimina) were compiled. Phylogenetic analysis indicated that Pseudonympha apparently originated in the Cape Fold Mountains about 15 Mya ago and spread steadily eastwards and northwards along the Great Escarpment during the aridification of the region, perhaps assisted by orogeny in the east and oceanic cooling in the west. Aridification cycles seem to have intermittently isolated some early lineages in elevated habitats in the interior, so that those lineages show lower speciation rates (or perhaps higher extinction rates) than those in the east. Four species delineation techniques indicated that some species are taxonomically oversplit. Based on genetic polyphyly and morphological similarity, we propose that the status of P. swanepoeli be reduced to that of a subspecies of P. varii, such that all the north-eastern populations from Harrismith to Tzaneen fall under P. varii swanepoeli van Son stat. n., and all the southern populations fall under P. varii varii van Son stat. n. Ultimately, the diversification of both of these lineages seems tied to their host plants’ response to aridification brought on by continental drift and orogeny. Sympatric organisms (eg cicadas) with biologies focused around different resources (eg savanna trees) show other patterns of diversification. The phylogenetic analysis of the subtribe Ypthimina also supports the monophyly of Paternympha, paraphyly of Ypthima, recognition of Thymipa Moore stat. rev. as a phylogenetic independent genus, and new relationships for Strabena. http://www.zoobank.org/urn:lsid:zoobank.org:pub:C3B34CBC-4BC2-44F3-8349-9DBC82FFBBF3

Integrative revision of the Blommersia wittei complex, with description of a new species of frog from western and north-western Madagascar.

Frogs of the Blommersia wittei complex are widespread in western and northern Madagascar, and are one of two clades of the family Mantellidae that have colonized the Comoran island of Mayotte. Based on a comprehensive set of DNA sequences of the mitochondrial 16S rRNA gene and the nuclear-encoded RAG1 and SACS genes, integrated with morphological and bioacoustic data, we here analyze the genetic differentiation of populations of this complex across Madagascar. We confirm that a candidate species named B. sp. Ca5 in previous studies represents a genetically well-defined evolutionary lineage distributed over much of western Madagascar, which we describe herein as Blommeria bara sp. nov. based on its molecular and bioacoustic differentiation. Blommersia wittei occurs across northern Madagascar but its type locality Ambanja, at the lower Sambirano river, is very close to the range of another, newly discovered microendemic lineage that was only found at two sites along the upper Sambirano river (here named as candidate species B. sp. Ca12). The B. wittei complex thus provides an example of a clade of closely related Malagasy frogs that contains species widespread over hundreds of kilometers, as well as extreme microendemics. For a full resolution of this species complex, more data need to be collected on the geographical contact among these two lineages, on the morphology and bioacoustics of B. sp. Ca12, and on the north-eastern populations of B. wittei at Sambava, which are weakly differentiated in mitochondrial genes but differ in bioacoustics and possibly in the extent of foot webbing.

#3507 IV CYCLOPHOSPHAMIDE VERSUS MYCOPHENOLATE MOFETIL AS INDUCTION REGIMEN IN PROLIFERATIVE LUPUS NEPHRITIS: A STUDY FROM NORTH-EAST INDIA

Abstract Background and Aims SLE is a chronic autoimmune disorder that can affect all organ systems. Clinically evident renal disease known as Lupus Nephritis (LN) occurs in upto 50% patients of SLE and upto 10% of LN patients develop ESRD. LN carries a significant morbidity and mortality and requires an early aggressive management. Our Aim is to study the effect of IV Cyclophosphamide (CYC) vs Mycophenolate Mofetil (MMF) as Induction regimen in proliferative Lupus Nephritis patients of North- East India. Method This is a prospective observational study conducted in the department of Nephrology, Gauhati Medical College, over a period of 1 year. Haematological and biochemical assay including serum creatinine, blood urea, serum albumin, ANA, Anti ds DNA, C3 and C4,24h urinary protein, estimated glomerular filtration rate (eGFR) of all patients were taken into account. Renal biopsy was performed under ultrasonographic guidance. SLEDAI Score and Activity and Chronicity Indexes were calculated for all patients. Statistical analysis was done by SPSS Version 22 for windows. Two tailed p<0.05 was considered to be statistically significant. A total of 64 biopsy proven LN patients of Class III, Class IV and Class V (Plus Class III/ Class IV) were enrolled in the study. We randomly assigned 34 patients with Class III through V lupus nephritis to IV CYC (NIH protocol/monthly) and 30 patients to MMF (2 gm/day) for 24 weeks as Induction Regimen. Both the groups received prednisone, tapered from a maximum starting dosage of 60 mg/day. All the patients were followed up for 6 months. Complete Response (CR) was considered when proteinuria<0.5g/g and Partial Response (PR) when proteinuria< 3g/g or there is reduction in proteinuria by at least 50%. Baseline characteristics and CR and PR were compared between the two groups. Results Of the total 64 patients, 57 patients (89%) were female, and 7 patients were male (11%) with the mean age of 31± 9.45 years. 24% patients had Class III LN and 76% had class IV LN. Complete Response was achieved in 13 patients (43%) in the MMF group and in 15 patients (44%) in CYC group. Partial Response was achieved in 11 patients (36.67%) in the MMF group and in 12 patients (35%) in the CYC group. There was a non-significant statistical difference between the two groups (p value ≥0.05 for both CR and PR). Conclusion The Northeastern population of India consists of various ethnic groups and there are records of variation in response to the Regimens in different geographical areas. In our study from North-east India, IV Cyclophosphamide and Mycophenolate Mofetil showed similar efficacy as Induction Regimen in proliferative Lupus Nephritis. However, there were higher rates of infection in the Cyclophosphamide group.

Prevalence of Type 2 Diabetes, Impaired Fasting Glucose, and Diabetes Risk in an Adult and Older North-Eastern Portuguese Population.

The aims of this study were (1) to evaluate the prevalence of type 2 diabetes (T2D) in a middle-aged north-eastern Portuguese population, (2) to analyze the prevalence of impaired fasting glucose (IFG), and (3) to assess the risk of T2D in this community-based sample. An exploratory, retrospective, and cross-sectional study was conducted from a total of 6570 individuals aged 18-102 years, among which 3865 were women (57.4 ± 18.1 years) and 2705 were men (60.0 ± 16.8 years). T2D diagnosis, IFG, and the diabetes risk score (low to very high risk) were assessed. The prevalence of T2D in this adult and an older north-eastern Portuguese population was 17.4%. A higher prevalence of T2D was reported in men (22.2%) than in women (14.0%); however, this was without significant differences (p = 0.086). Otherwise, the prevalence of T2D was significantly different among the age groups and increased with age (p < 0.001). Regarding IFG, a higher percentage of cases was observed in men (14.1%) than in women (8.4%) (p < 0.001). The risk of developing T2D in the next 10 years showed an association with sex and age group (p < 0.001) with a small-to-moderate effect (V = 0.1-0.3). Men and the elderly had the highest percentage of cases in the moderate-to-very high-risk bands. The current research confirmed a higher prevalence of T2D, IFG, and diabetes risk than previous Portuguese epidemiological reports. The results also suggest potential prediabetes cases, which should be carefully monitored. The current research adds evidence to the worldwide trend of the increasing prevalence of T2D and intermediate hyperglycemia (i.e., prediabetes).

A serological survey of pathogens associated with the respiratory and digestive system in the Polish European bison (Bison bonasus) population in 2017–2022

BackgroundThe European bison (Bison bonasus) is a near threatened species and requires health monitoring. The aim of the present study was to determine the prevalence of antibodies to pathogens known to cause respiratory and digestive illness in ruminants.ResultsIn the studied 328 European bison, the highest seroprevalence was observed for Bovine herpesvirus-1 (BoHV-1) (50.27%), Bovine Coronavirus (BCoV) (26.36%), and Bluetongue Virus (BTV) (12.83%). For Mycoplasma bovis strains and Bovine Viral Diarrhea Virus (BVDV), positive results were rare. Interestingly, a higher prevalence of BTV antibodies was noted in the northeastern populations and older animals.ConclusionsOur findings indicate that the Polish European bison population appears to have considerable contact with BoHV-1; however, this does not appear to be of great significance, as clinical symptoms and post-mortem lesions are rarely noted in Polish European bison population. The high seroprevalence of BTV in the north-east of Poland is an ongoing trend, also noted in previous studies. It is possible that European bison may perpetuate the virus in this region. This is the first report of antibodies for BCoV in European bison.

Thyroid Dysfunction and Chronic Kidney Disease: A Study Among the Northeastern Population of India.

Chronic kidney disease (CKD) is a multifaceted non-communicable disease characterized by a progressive decline in kidney function ultimately requiring renal replacement therapy (RRT) in most patients. Due to the high cost and availability of a limited number of donors, the majority of patients dependon dialysis and conservative management. Thyroid hormones are indispensable for the growth, development, and homeostasis of our body. The kidney plays an important role in the metabolism, degradation, and excretion of thyroid hormones. Various studies have revealed significant dysfunction in thyroid hormone status in CKD patients, but the results are inconsistent. To evaluate and compare the thyroid hormone status in CKD patients with healthy controls along with a comparison of thyroid hormones in CKD patients on regular hemodialysis with those on conservative management. The present cross-sectional study involved 100 subjectsof both sexes between 40 and 70 years of age, out of which 50 were patients of stage 5 CKDwith no previous history of any thyroid disorders, while 50 apparently healthy subjects served as control. Of the CKD patients,52% were on regular hemodialysis while 48% were receiving conservative care. The participants were investigated for various biochemical parameters like blood urea, serum creatinine, total triiodothyronine (TT3), total thyroxine (TT4), and thyroid stimulating hormone (TSH). The estimated glomerular filtration rate (eGFR) was calculated using a modification of diet in renal disease (MDRD) 4 variable formula. The thyroid profiles were also compared between patients of CKD receiving conservative management and those on maintenance hemodialysis. Of the total sample, 35 (70%) were male and 15 (30%) were female in each of the case and control groups. The mean ageof CKD patients and the control group was 55.32 ± 9.62 years and 54.48 ± 9.63 years, respectively. TT3 was reduced in all50 CKD patients. TT4 was normal in 31 (62%), reduced in 18 (36%), and high in one (2%) case. TSH was high in 38 (76%) cases, while reduced in one (2%) and normal in 11 (22%) cases. The mean blood level of TT3 and TT4 showed a statistically significant reduction (P < 0.0001 for each), while the TSH level showed a significant increase with a p-value of 0.0002 in CKD patients compared to controls. The mean blood urea and serum creatinine levels were statistically increased in cases than in controls (P < 0.0001). The thyroid hormone status revealed a significant difference between CKD patients on maintenance hemodialysis compared to those on conservative care with a p-value of 0.0005 for TT3, 0.0006 for TT4, and 0.0055 for TSH. Patients with CKD were at risk of thyroid hypofunction irrespective of their mode of treatment. This study highlights the clinically relevant interactions between renal and thyroid function, which may be helpful to clinicians for optimal diagnosis and management of CKD patients.

SEXY CHINKIES IN INDIAN CITIES: CAN WE EMBRACE A SLANT-EYED MARY?

This article investigates the escalation of anti-northeastern racism during the COVID-19 pandemic in India, by analysing the existing and underlying forms of domination faced by north-eastern Indian populations living in the metropolitan cities of India. It particularly investigates the intersectionalities of caste and race, gender, LGBT, and the older form of anti-Chinese sentiment called the yellowperil myth. It explores Mary Magdalene’s life and reflects on the public and cultural narrative, while simultaneously highlighting the lived experiences of north-eastern women in Indian cities. The article compares the experience of Mary Magdalene with that of the indigenous northeastern women. It asks how Mary, if she were slant-eyed, negotiated the humiliation and discrimination of race and gender, and how the figure of Mary can help challenge the public myth and offer a site of resistance for north-eastern women, many of whom are Christian.

Increased prevalence of the founder BRCA1 c.5309G>T and recurrent BRCA2 c.1310_1313delAAGA mutations in breast cancer families from Northerstern region of Morocco: evidence of geographical specificity and high relevance for genetic counseling

BackgroundInherited mutations in the breast cancer susceptibility genes BRCA1 and BRCA2 (BRCA1/2) confer high risks of breast and ovarian cancer. Because the contribution of BRCA1/2 germline mutations to BC in the Northeastern population of Morocco remains largely unknown, we conducted this first study to evaluate the prevalence and the phenotypic spectrum of two BRCA1/2 pathogenic mutations (the founder BRCA1 c.5309G>T and BRCA2 c.1310_1313delAAGA). This choice was also argued by the presence of an apparent specific geographical connection of these mutations and the Northeastern region of Morocco.MethodsScreening for the germline mutations c.5309G>T and BRCA2 c.1310_1313delAAGA was performed by sequencing on a total of 184 breast cancer (BC) patients originated from the Northeastern region of Morocco.The likelihood of identifying a BRCA mutation is calculated using the Eisinger scoring model. The clinical and pathologic features were compared between the BRCA-positive and BRCA-negative groups of patients. Difference in survival outcomes was compared between mutation carriers and non-carriers.ResultsBRCA1 c.5309G>T and BRCA2 c.1310_1313delAAGA are responsible for a significant proportion of all BC cases (12.5%) and at least 20% of familial BC. The screening of BRCA1/2 genes by NGS sequencing confirmed that there are no additional mutations detected among positive patients.The clinicopathological features in positive patients were in accordance with typical characteristics of BRCA pathogenic mutations. The mean features in the carriers were the early onset of the disease, familial history, triple negative status (for BRCA1 c.5309G>T) and worse prognosis in terms of overall surviving.Our study indicates that the Eisinger scoring model could be recommended to identify patients for referral to BRCA1/2 oncogenetic counseling.ConclusionOur findings suggest that BRCA1 c.5309G>T and BRCA2 c.1310_1313delAAGA mutations may have a strong founder and/or recurrent effect on breast cancer among the Northeastern Moroccan population. There contribution to breast cancer incidence is certainly substantial in this subgroup. Therefore, we believe that BRCA1 c.5309G>T and BRCA2 c.1310_1313delAAGA mutations have to be included in the array of tests aimed at revealing cancer syndrome carriers among subjects of Moroccan origin.
