Identification of mutations in the S gene of hepatitis B virus in HIV positive Mexican patients with occult hepatitis B virus infection

Annals of Hepatology, 2020
Introduction and aim: Occult hepatitis B virus infection (OBI) is characterized by the presence of replication-competent hepatitis B virus (HBV) DNA in the liver and/or serum of patients with undetectable levels of the HBV surface antigen (HBsAg). Due to

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis

Laser &Photonics Reviews, EarlyView.
We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Diagnosis of Urethral Resistance in Men: 70 Years of History

Neurourology and Urodynamics, EarlyView.
ABSTRACT Background and Aims The urethral resistance (UR) is one of the key outcomes of the urodynamic pressure‐flow study (PFS) in men. Combined with a clinical meaningful cut‐off point, urodynamic bladder outflow obstruction (BOO) can be determined. This characterization of BOO provides guidance in the management of lower urinary tract symptoms (LUTS)

Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

Phytotherapy Research, EarlyView.
ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.
