Whole genome sequencing of three native chicken varieties (Common Deshi, Hilly and Naked Neck) of Bangladesh.

Bangladeshi indigenous chicken varieties - Common Deshi, Hilly and Naked Neck are notable for their egg production, meat quality, extraordinary survivability and disease resistance. However, the potential to harness their unique genetic merits are being eroded by various factors, including crossbreeding. In-depth genomic studies have not been carried out on these breeds so far.

Episodic Aspects of a Path Navigated Through Hippocampal Neurobiology.

As requested by the editors of this special issue of Hippocampus on Scientific Histories of Hippocampal Research, this review provides a detailed personal perspective and historical background on the research involved in a number of findings. The review includes description of the development of the water maze and its use in providing evidence to support the role of the hippocampus in spatial memory function. The review also describes how the water maze was then used in further work to support the proposal that NMDA-dependent synaptic modification in the hippocampus mediates the encoding of new spatial memories.

Understanding cervical cancer prevention in Africa: a qualitative systematic review of the role of men.

Background: Cervical cancer (CC) is a preventable noncommunicable disease if detected early through screening for precancers and appropriately managed. The causal link with high-risk human papillomavirus infection is established, making elimination possible through the WHO multipronged 90:70:90 strategy. However, practical CC elimination efforts need to address issues within the sociocultural context that can facilitate or hinder prevention strategies.

Lifetime depression, sleep disruption and brain structure in the UK Biobank cohort.

Whether depression and poor sleep interact or have statistically independent associations with brain structure and its change over time is not known. Within a subset of UK Biobank participants with neuroimaging and subjective and/or objective sleep data (n = 28,351), we examined associations between lifetime depression and sleep disruption and their interaction with structural neuroimaging measures, both cross-sectionally and longitudinally. Sleep variables were: self-reported insomnia and difficulty getting up; actigraphy-derived short sleep (<7 h); sustained inactivity bouts during daytime (SIBD); and sleep efficiency.

Cephalomedullary Nailing for Subtrochanteric and Reverse-Oblique Femoral Fractures: Comparison of a Single Versus Dual Lag Screw Device.

Background: Subtrochanteric proximal femoral fractures are generally treated with cephalomedullary nail fixation. We aimed to compare outcomes of subtrochanteric fracture fixation using a single lag screw (Gamma3 nail, GN) or dual lag screw (INTERTAN nail, IN) device.

Methods: The primary outcome measure was mechanical failure, defined as lag screw cut-out or back-out, nail breakage, or peri-implant fracture.

ZYG-12/Hook's dual role as a dynein adaptor for early endosomes and nuclei is regulated by alternative splicing of its cargo binding domain.

The microtubule motor cytoplasmic dynein-1 transports and positions various organelles, but the molecular basis of this functional diversity is not fully understood. Cargo adaptors of the Hook protein family recruit dynein to early endosomes (EE) in fungi and human cells by forming the FTS-Hook-FHIP (FHF) complex. By contrast, the Hook homolog ZYG-12 recruits dynein to the nuclear envelope (NE) in the meiotic gonad and mitotic early embryo by forming a Linker of Nucleoskeleton and Cytoskeleton (LINC) complex.

Next generation brain health: transforming global research and public health to promote prevention of dementia and reduce its risk in young adult populations.

Efforts to prevent dementia can benefit from precision interventions delivered to the right population at the right time; that is, when the potential to reduce risk is the highest. Young adults (aged 18-39 years) are a neglected population in dementia research and policy making despite being highly exposed to several known modifiable risk factors. The risk and protective factors that have the biggest effect on dementia outcomes in young adulthood, and how these associations differ across regions and groups, still remain unclear.

A Systematic Review and Meta-Analysis of the Efficacy and Safety of Combined Mechanical Circulatory Support in Acute Myocardial Infraction Related Cardiogenic Shock.

Background: Acute myocardial infarction-related cardiogenic shock (AMICS) is a severe complication associated with exceedingly high mortality rates. While mechanical circulatory support (MCS) has emerged as a potential intervention, the evidence base for independent MCS use remains weak. In contrast, systematic reviews of observational studies have revealed significant mortality reduction when a combination of MCS was used: VA-ECMO in conjunction with a left ventricular (LV) unloading device (Impella or IABP).

A multi-valent polymyxin-based fluorescent probe for the detection of Gram-negative infections.

A multi-branched fluorogenic probe for the rapid and specific detection of Gram-negative bacteria is reported. Three Gram-negative-targeting azido-modified polymyxins were clicked onto a trivalent scaffold functionalised with the environmental green-emitting fluorophore 7-nitrobenz-2-oxa-1,3-diazole. The probe allowed wash-free detection of target bacteria with increased sensitivity and lower limits of detection compared to monovalent probes.

Linking Foraging Behaviour and Habitat Preferences During Moult Across Multiple Populations of Red-Throated Diver.

Understanding the habitat use of individuals can facilitate methods to measure the degree to which populations will be affected by potential stressors. Such insights can be hard to garner for marine species that are inaccessible during phases of their annual cycles. Here, we quantify the link between foraging habitat and behaviour in an aquatic bird of high conservation concern, the red-throated diver () across three breeding populations (Finland, Iceland and Scotland) during their understudied moult period.

The mediating role of rumination in the relationship between negative cognitive styles and depression among pregnant women in Guangzhou, China.

Backgrounds: Negative cognitive styles (NCSs) have been identified as risk factor for the onset of depression. However, little empirical evidence is available to support its role in psychological disorders in the perinatal period. Moreover, less is known about the underlying mechanism in the relation between NCSs and depression in pregnant women.

Identification of Pappa and Sall3 as Gli3 direct target genes acting downstream of cilia signaling in corticogenesis.

The cerebral cortex is critical for advanced cognitive functions and relies on a vast network of neurons to carry out its highly intricate neural tasks. Generating cortical neurons in accurate numbers hinges on cell signaling orchestrated by primary cilia to coordinate the proliferation and differentiation of cortical stem cells. While recent research has shed light on multiple ciliary roles in corticogenesis, specific mechanisms downstream of cilia signaling remain largely unexplored.

Alterations in white matter microstructure in bipolar disorder patients with and without psychosis.

Objective: The overlap of affective disturbance and psychosis considerably makes it complex to determine the etiology of bipolar disorder (BD) and develop targeted interventions. The present study aimed to determine the white matter microstructural alterations that distinguish between BD with psychosis (BDP) and BD with no psychosis (BDNP) to identify patients who may specifically benefit from appropriately effective treatments.

Methods: Diffusion-weighted magnetic resonance images were acquired from 38 participants with BDP, 52 participants with BDNP and 70 healthy controls (HCs).

Association of preconception premenstrual disorders with perinatal depression: an analysis of the perinatal clinical database of a single Japanese institution.

Background: Recent studies have identified premenstrual disorders (PMDs) as a risk factor for postpartum depression. However, routine screening for preconception PMDs is not yet common in Japan. This study investigated the association between preconception PMDs and perinatal depression in a single tertiary care setting.

Methods: The survey comprised four sections, to investigate the sociodemographic characteristics of mothers and their babies, Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF), the Edinburgh Postnatal Depression Scale (EPDS) of mothers, and features associated with BR. The survey was administered online to those with babies aged 0-24 months.

Citizen science in eDNA monitoring for mediterranean monk seal conservation.

Background: Citizen Science (CS) offers a promising approach to enhance data collection and engage communities in conservation efforts. This study evaluates the use of CS in environmental DNA (eDNA) monitoring for Mediterranean monk seal conservation. We validated CS by assessing the effectiveness of a newly developed CS-friendly filtration system called "WET" (Water eDNA Trap) in eDNA detection, addressing technical challenges, and analysing volunteer faults.

Encompassing view of spatial and single-cell RNA sequencing renews the role of the microvasculature in human atherosclerosis.

Atherosclerosis is a pervasive contributor to ischemic heart disease and stroke. Despite the advance of lipid-lowering therapies and anti-hypertensive agents, the residual risk of an atherosclerotic event remains high, and developing therapeutic strategies has proven challenging. This is due to the complexity of atherosclerosis with a spatial interplay of multiple cell types within the vascular wall.

Inter-chromosomal transcription hubs shape the 3D genome architecture of African trypanosomes.

The eukaryotic nucleus exhibits a highly organized 3D genome architecture, with RNA transcription and processing confined to specific nuclear structures. While intra-chromosomal interactions, such as promoter-enhancer dynamics, are well-studied, the role of inter-chromosomal interactions remains poorly understood. Investigating these interactions in mammalian cells is challenging due to large genome sizes and the need for deep sequencing.

Data sharing in circadian rhythm and mental health research: current status, challenges, recommendations and future directions.

Data sharing is a cornerstone of modern scientific research, playing a critical role in fostering greater collaboration, enhancing reproducibility, transparency and efficiency of scientific discoveries, and integrating diverse data sources. In circadian rhythm research, data sharing is particularly important due to the complexity and heterogeneity of the data, which includes molecular profiles, physiological measurements, clinical data and sensor-based data. UK research funders, such as Medical Research Council, Wellcome Trust and UK Research and Innovation, have established data-sharing policies to promote open science and enhance research transparency.

Outcomes for Younger Patients with Femoral Neck Fractures.

Background: There is a paucity of longer-term outcome data in younger adult patients who undergo fixation for an intracapsular hip fracture. The aims of this study were to evaluate the outcomes for young adult patients undergoing intracapsular hip fracture fixation and to assess factors associated with failure and patient-reported outcome measures (PROMs).

Methods: From 2008 to 2018, 112 consecutive patients ≤60 years of age (mean age, 48 years [range, 20 to 60 years]; 54% male) were retrospectively identified as having undergone fixation of an intracapsular hip fracture.

Reading the family: A constructivist grounded theory on organ donation conversations.

Approaching families to discuss deceased organ donation authorisation is considered one of the central stages of the organ donation process. In many countries, specialist nurses lead the organ donation process, approach and support families. However, how these encounters occur is not yet fully understood.

Invasive or Non-invasive Vagus Nerve Stimulation Modulation of Brain Function and Remodeling After Stroke: a Review.

Background: The main reason restricting stroke patients from reintegrating into society is neurological deficits. Of particular interest is the potential Vagus Nerve Stimulation (VNS) potentially offers for sustaining improvement in neurological deficits. The goal of the present study is to provide a summary of the findings from research that has been carried out to elucidate the mechanisms and demonstrate the efficacy and safety of the clinical application of VNS, as well as to identify research gaps in the field, in order to offer references for subsequent further research and application.
