Galantamine-Memantine Combination in the Treatment of Parkinson's Disease Dementia.

Parkinson's disease (PD) is a progressive neurodegenerative disorder that affects over 1% of population over age 60. It is defined by motor and nonmotor symptoms including a spectrum of cognitive impairments known as Parkinson's disease dementia (PDD). Currently, the only US Food and Drug Administration-approved treatment for PDD is rivastigmine, which inhibits acetylcholinesterase and butyrylcholinesterase increasing the level of acetylcholine in the brain.

Maternal and infant predictors of human milk macronutrient and energy concentrations in rural Bangladesh: an observational cohort study.

Background: Human milk macronutrient (protein, fat, and carbohydrate) and energy concentrations vary based on maternal and infant factors and time postpartum.

Objective: To determine the change in milk macronutrient and energy concentrations from approximately 2 to 5 months postpartum and identify factors associated with this variation among a lactation cohort in Bangladesh.

Methods: In this prospective observational lactation cohort in rural Sylhet, Bangladesh, we collected hand-expressed mid-feed human milk samples and analyzed macronutrient concentrations using mid-infrared spectroscopy.

Opportunities and challenges for human microphysiological systems in drug development.

Microphysiological systems (MPS) are complex in vitro tools that incorporate cells derived from various healthy or disease-state human or animal tissues and organs. While MPS have limitations, including a lack of globally harmonized guidelines for standardization, they have already proven impactful in certain areas of drug development. Further research and regulatory acceptance of MPS will contribute to making them even more effective tools in the future.

This study was intended to assess the delay encountered by the patients and its consequences in the process of diagnosis and treatment of bladder cancer.

Functional Outcome of Subtrochanteric Femoral Fractures Fixation by Proximal Femoral Locking Compression Plate.

Subtrochanteric femoral fractures are one of the common fractures encountered in today's Orthopaedic practice. This area consists of mostly cortical bone with high stress generation thus heal slowly which leads implant failure. The inherent instability of this fracture and forces of the muscles with comminuted medial calcar is giving the fracture a tendency to varus collapse.

Molecular Characterization of δβ Thalassemia/Hereditary Persistence of Fetal Hemoglobin and Its Correlation With Clinical and Hematological Profile; a Single Center Study in North India.

Background: δβ-thalassemia/HPFH is an uncommon hemoglobinopathy characterized by decreased or the total absence of production of δ- and β-globin and increased HbF levels. Both these disorders have variable genotype and phenotype, but significant overlap in the clinical and laboratory findings. Given the lack of literature in this regard, the study aimed to estimate the prevalence of the disease and evaluate its clinical, hematological, and molecular profile in India.

Network Pharmacology and In Silico Elucidation of Phytochemicals Extracted from Ajwa Dates (Phoenix dactylifera L.) to Inhibit Akt and PI3K Causing Triple Negative Breast Cancer (TNBC).

Background: About 10-15% of all breast cancers comprise triple-negative breast cancer (TNBC), defined as cancer cells that lack receptors for the ER, PR, and HER2 protein receptors. Due to the absence of these receptors, treating TNBC using conventional chemotherapy is challenging and, therefore, requires the discovery of novel chemotherapeutic agents derived from natural sources.

Objective: The current work was intended to study the potential phytochemicals of Ajwa dates (Phoenix dactylifera L.

Promising selective alpha-1 blocker silodosin as a new therapeutic strategy for premature ejaculation and analysis of its drug adverse effect: A systematic review and meta-analysis of randomized controlled trials.

Introduction And Objectives: Premature Ejaculation (PE) occurs in 31% of men aged 18-59 years, leading to disappointment and avoidance of sexual relations. The current guideline of treatment for PE is Dapoxetine, which possesses several adverse effects causing the limitation of its long-term use. Silodosin, an alpha-1 blocker, has been proposed as a new option for treating PE due to its minimal side effects.

Ion-induced surface reactions and deposition from Pt(CO)Cl and Pt(CO)Br.

Ion beam-induced deposition (IBID) using Pt(CO)Cl and Pt(CO)Br as precursors has been studied with ultrahigh-vacuum (UHV) surface science techniques to provide insights into the elementary reaction steps involved in deposition, complemented by analysis of deposits formed under steady-state conditions. X-ray photoelectron spectroscopy (XPS) and mass spectrometry data from monolayer thick films of Pt(CO)Cl and Pt(CO)Br exposed to 3 keV Ar, He, and H ions indicate that deposition is initiated by the desorption of both CO ligands, a process ascribed to momentum transfer from the incident ion to adsorbed precursor molecules. This precursor decomposition step is accompanied by a decrease in the oxidation state of the Pt(II) atoms and, in IBID, represents the elementary reaction step that converts the molecular precursor into an involatile PtX species.

An In Silico Approach to Discover Efficient Natural Inhibitors to Tie Up Epstein-Barr Virus Infection.

Epstein-Barr virus (EBV), also known as human herpesvirus 4, is a member of the herpes virus family. EBV is a widespread virus and causes infectious mononucleosis, which manifests with symptoms such as fever, fatigue, lymphadenopathy, splenomegaly, and hepatomegaly.

Parkinson's Disease: Biomarkers for Diagnosis and Disease Progression.

Parkinson's disease (PD) is a progressive neurological disease that causes both motor and nonmotor symptoms. While our understanding of putative mechanisms has advanced significantly, it remains challenging to verify biomarkers with sufficient evidence for regular clinical use. Clinical symptoms are the primary basis for diagnosing the disease, which can be mild in the early stages and overlap with other neurological disorders.
