A GWAS identifies FSHR rs2300441 associated with Follicle‐stimulating Hormone levels
Abstract Follicle stimulating hormone (FSH) and luteinizing hormone (LH) play critical roles in female reproduction, while the underlying genetic basis is poorly understood. GWASs of FSH and LH levels were conducted in 2590 Chinese females including 1882 PCOS cases and 708 controls. GWAS for FSH level identified multiple variants at FSHR showing genome‐wide significance with the top variant (rs2300441) located in the intron of FSHR. The A allele of rs2300441 led to a reduced level of FSH...

A nonsense variant in NME5 causes human primary ciliary dyskinesia with radial spoke defects
ABSTRACT Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disorder characterized by defects in the function or structure of motile cilia. In most cases, causative variants result in axonemal dynein arm anomalies, however, PCD due to radial spoke (RS) and central pair (CP) of microtubules has been rarely reported. To identify the molecular basis of PCD characterized by RS/CP defects, we performed whole exome sequencing in PCD patients with RS/CP defects. We identified a homozygous...

Encephalopathy due to defective mitochondrial and peroxisomal fission 2 caused by a novel MFF gene mutation in a young child
Abstract Encephalopathy due to defective mitochondrial and peroxisomal fission 2 caused by MFF (mitochondrial fission factor) gene mutation is a rare neurogenetic disorder. Pathogenic MFF mutations have been described in three reports in literature till date. We report a young child of Indian descent who presented to us with global developmental followed by regression of acquired milestones, spasticity, visual and auditory impairment, and was found to harbour a novel pathogenic homozygous...

Regulatory effect of 17β‐estradiol on the expression of β‐defensin‐2 and proinflammatory cytokines in human oral epithelial cells
Abstract Background Although estrogen deficiency has been proposed as a risk factor for oral mucosal inflammatory diseases in post‐menopausal women, the mechanisms involved remain unclear. This study aimed to investigate the effect of 17β‐estradiol (E2) on the inflammatory response stimulated by interleukin‐1 beta (IL‐1β) in human oral mucosal epithelial cells (hOMECs) and its possible mechanism. Methods Primary hOMECs were obtained from female infants and cultured in keratinocyte...

What is the most effective policy response to the new coronavirus pandemic?
Disclaimer: I am not an epidemiologist, but there is an interesting potentially important pattern in the data that seems worth understanding. World healthcare authorities appear to be primarily shifting towards Social Distancing. However, there is potential to pursue a different strategy in the medium term that exploits a vulnerability of this disease: the 5 day incubation time is much longer than a 4 hour detection time. This vulnerability is real—it has proved exploitable at scale in South...

Multidimensional Coculture System to Model Lung Squamous Carcinoma Progression
An in vitro model system was developed to capture tissue architectural changes during lung squamous carcinoma (LUSC) progression in a 3-dimensional (3D) co-culture with cancer-associated fibroblasts (CAFs). This organoid system provides a unique platform to investigate the roles of diverse tumor cell-intrinsic and extrinsic changes that modulate the tumor phenotype.

Capturing the Cardiac Injury Response of Targeted Cell Populations via Cleared Heart Three-Dimensional Imaging
Cardiomyocyte proliferation following injury is a dynamic process that requires a symphony of extracellular cues from non-myocyte cell populations. Utilizing lineage tracing, passive CLARITY, and three-dimensional whole-mount confocal microscopy techniques, we can analyze the influence of a variety of cell types on cardiac repair and regeneration.

Regulatory T cells specifically suppress conventional CD8αβ T cells in intestinal tumors of APC Min/+ mice
Abstract The presence of activated T cells in colorectal cancer tissues is a strong predictor of patient survival. Our previous studies have shown that regulatory T cells (Treg) are able to reduce T cell transendothelial migration in vitro and accumulation of effector T cells in intestinal tumors in vivo in the murine APCMin/+ model for microsatellite stable intestinal tumors. In this study, we investigated the effect of Treg depletion on the density and effector functions of...

Ratio of T1-Weighted to T2-Weighted Signal Intensity as a Measure of Tissue Integrity: Comparison with Magnetization Transfer Ratio in Patients with Multiple Sclerosis [ADULT BRAIN]
SUMMARY:The study aim was to compare the ratio of T1WI to T2WI signal intensity (T1/T2) with magnetization transfer ratio, a marker of myelin integrity, in patients with multiple sclerosis. A moderate correlation (r = 0.50, P = .034) was found between the magnetization transfer ratio and T1/T2 in normal-appearing gray matter, and a strong correlation for normal-appearing white matter (r = 0.63, P = .005) and lesions (r = 0.70, P = .001). Results suggest that besides myelin integrity, other factors...

Carotid Vessel Wall Imaging on CTA [EXTRACRANIAL VASCULAR]
SUMMARY:Vessel wall imaging has been increasingly used to characterize plaque beyond luminal narrowing to identify patients who may be at the highest risk of cerebrovascular ischemia. Although detailed plaque information can be obtained from many imaging modalities, CTA is particularly appealing for carotid plaque imaging due to its relatively low cost, wide availability, operator independence, and ability to discern high-risk features. The present Review Article describes the current understanding...
