Article Synopsis
  • - Research on patients with normal pressure hydrocephalus (NPH) indicates that early Alzheimer's disease (AD) pathology can be detected, and this study aims to identify cerebrospinal fluid (CSF) biomarkers related to these initial AD changes.
  • - The study analyzed CSF data and found that specific biomarkers such as β-amyloid-42/40 and neurofilament light chain (NfL) are correlated with AD pathology; seven key proteins were identified that also relate to both pathology and gene expression.
  • - The findings suggest a link between CSF biomarkers and central nervous system changes in AD, providing valuable insights into how these markers reflect the disease's progression.

Article Synopsis
  • * Key reproductive genes, including kiss2, gnrh1, and their receptors, showed decreased expression at higher temperatures (37 °C), leading to reduced gonadotropin levels in the pituitary.
  • * Histological analysis revealed normal gamete growth at a control temperature (31 °C), but slowed spermatogenesis and oocyte maturation, along with atretic oocytes, at the higher temperature (37 °C).

Introduction: Normal pressure hydrocephalus (NPH) patients undergoing cortical shunting frequently show early AD pathology on cortical biopsy, which is predictive of progression to clinical AD. The objective of this study was to use samples from this cohort to identify CSF biomarkers for AD-related CNS pathophysiologic changes using tissue and fluids with early pathology, free of post-mortem artifact.

Methods: We analyzed Simoa, proteomic, and metabolomic CSF data from 81 patients with previously documented pathologic and transcriptomic changes.

Dementia is a chronic disorder of the brain that affects cognitive performance. The caregivers of individuals with dementia experience a greater burden that affects their Quality of Life (QoL). This cross-sectional study conducted in India was designed to assess the caring burden and QoL among the caregivers of people with dementia, as well as to ascertain the relationship between QoL scores and burden.

Background: South and South-East Asian countries report a great liability for the world's road traffic injuries (RTIs) and deaths. A vast number of research studies tested various interventions including specific protective devices to prevent accidents, but no review papers have been conducted to find out the prevalence of RTIs in South-East and South Asian countries.

Objective: This review paper was an attempt to find out the prevalence of RTIs and their associated factors in South-East and South Asian countries.

Background: Advances in treatment for patients with Diffuse Large B-Cell Lymphoma (DLBCL) have led to improved patient outcomes but the magnitude of these disparities remains understudied with regards to improved survival outcomes. We sought to describe changes in DLBCL survival trends over time and explore potential differential survival patterns by patients' race/ethnicity and age.

Methods: We utilized the Surveillance, Epidemiology, and End Results (SEER) database to identify patients diagnosed with DLBCL from 1980 to 009 and determined 5-year survival outcomes for all patients, categorizing patients by year of diagnosis.

Coke-oven wastewater (CW), containing an array of toxic pollutants above permissible limits even after conventional primary and secondary treatment, needs a tertiary (polishing) step to meet the statutory limit. In the present study, a suitable bacterial-microalgal consortium (Culture C) was constructed using bacterial (Culture B: Bacillus sp. NITD 19) and microalgal (Culture A: a consortium of Chlorella sp.

The lack of high-functioning p-type semiconductor oxide material is one of the critical challenges that face the widespread performance of transparent and flexible electronics. Cu O nanostructured thin films are potentially appealing materials for such applications because of their innate p-type semi-conductivity, transparency, non-toxicity, abundant availability, and low-cost fabrication. This review summarizes current research on Cu O nanostructured thin films deposited by the SILAR technique.

Toll-like receptor 4 (TLR4), a pattern recognition receptor, is activated by lipopolysaccharides (LPS) and induces the MyD88 pathway, which subsequently produces pro-inflammatory cytokines through activation of transcriptional nuclear factor (NF)-κB. Statins have been widely prescribed to reduce cholesterol synthesis for patients with cardiovascular disease. Statins may have pleiotropic effects, which include anti- and pro-inflammatory effects on cells.

Background And Objectives: Graft failure (GF) after cord blood transplant (CBT) has decreased with improved supportive care and cord selection strategies. We aimed to evaluate cord blood selection and factors associated with retransplantation on the incidence of GF, determine risk factors for GF including host antibodies to Kell antigen and evaluate survival after GF.

Materials And Methods: We retrospectively reviewed 84 patients who underwent CBT at the University of Oklahoma between 2000 and 2016 and compared outcomes in patients with/without engraftment by Day 28.

Toll-like receptor 4 (TLR4) is a receptor on an immune cell that can recognize the invasion of bacteria through their attachment with bacterial lipopolysaccharides (LPS). Hence, LPS is a pro-immune response stimulus. On the other hand, statins are lipid-lowering drugs and can also lower immune cell responses.

Background: Head and Neck Cancer (HNC) patients are at increased risk of psychosocial distress compared with patients with other forms of cancer. Various symptoms of the disease and side effects of treatment are attributing factors for distress. This systematic review aimed to identify the prevalence of psychosocial distress among HNC patients receiving radiotherapy.

Plasmacytoid dendritic cells [pDCs] represent a rare innate immune subset uniquely endowed with the capacity to produce substantial amounts of type-I interferons. This function of pDCs is critical for effective antiviral defenses and has been implicated in autoimmunity. While IFN-I and select cytokines have been recognized as pDC secreted products, a comprehensive agnostic profiling of the pDC secretome in response to a physiologic stimulus has not been reported.

The COVID-19 pandemic has led to significant global health and economic consequences. There is an unmet need to define a molecular fingerprint of severity of the disease that may guide an early, rational and directed intervention preventing severe illness. We collected plasma from patients with moderate (nine cases), severe (22 cases) and critical (five cases) COVID-19 within three days of hospitalization (approximately one week after symptom onset) and used a cytokine antibody array to screen the 105 cytokines included in the array.

The treatment landscape of chronic lymphocytic leukemia (CLL) has witnessed immense changes in the past decade. Several newer target therapies and their combinations with anti-CD 20 therapies have got approval for management of CLL in the treatment-naïve and relapsed/refractory setting. Also, the availability of newer diagnostic techniques has helped differentiate the disease into high- and low-risk CLL which acts not just as a prognostic marker but also helps decide the best drug management that can be administered to the patients.

Macrophages play a critical role in innate immunity through Toll-like receptor (TLR) signaling. Lipopolysaccharides (LPS) are a ligand of microbial origin that can trigger cell signaling in macrophages through TLRs and production of pro-inflammatory cytokines. Statin, a hypercholesterolemia drug, on the contrary, can reduce inflammatory cytokine production, and inflammation at large.

Chemical cross-linking is a powerful strategy for elucidating the structures of protein or protein complexes. The distance constraints obtained from cross-linked peptides represent the three-dimensional structures of the protein complexes. Unfortunately, structural analysis using cross-linking approach demands a significant amount of data to elucidate protein structures.

An inimitable urea-based multichannel chemosensor, [1,5-bis-(2,6-dichloro-4-(trifluoromethyl)phenyl)carbonohydrazide], was examined to be highly proficient to recognize CN based on the H-bonding interaction between sensor -NH moiety and CN in aqueous medium with explicit selectivity. In the absorption spectral titration of , a new peak at higher wavelength was emerged in titrimetric analytical studies of CN with the zero-order reaction kinetics affirming the substantial sensor-analyte interaction. The isothermal titration calorimetry (ITC) experiment further affirmed that the sensing process was highly spontaneous with the Gibbs free energy of -26 × 10 cal/mol.
