Bronchoscopic evaluation and final diagnosis in patients with chronic non productive cough with normal Chest X ray [PDF]

, 2010
When a proper detailed history, clinical examination, chest X ray and sputum analysis does not yield a definite diagnosis for the cause of chronic cough, bronchoscopy is indicated.

Calcium‐sensing receptor induces the apoptosis of chondrocytes in cooperation with phosphate transporter

FEBS Open Bio, EarlyView.
Excess Ca2+ ions activate the Calcium‐Sensing Receptor (CaSR), which subsequently drives the uptake of excess inorganic phosphate (Pi) via the Pi transporter (Pit−1) in chondrocytes. This mechanism causes a toxic increase in intracellular Pi concentration, ultimately leading to chondrocyte apoptosis and pathological mineralization. Excess extracellular

Engineered Panax notoginseng polysaccharide micelles inhibit macrophage polarization and delay the progression of rheumatoid arthritis via JAK2-STAT3 signaling pathway

Journal of Nanobiotechnology
Background The imbalance of macrophage polarization plays a pivotal role in the progression of rheumatoid arthritis (RA). Reprogramming macrophages from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype is considered a promising ...

Celastrol attenuates Alzheimer’s disease-mediated learning and memory impairment by inhibiting endoplasmic reticulum stress-induced inflammation and oxidative stress

Archives of Medical Science
Introduction Alzheimer’s disease (AD) is triggered by biological mechanisms such as neuroinflammation and oxidative stress. Endoplasmic reticulum (ER) stress can lead to the expression of molecular chaperones in the ER, which helps in restoring cellular ...

Impact of a senior research thesis on students' perceptions of scientific inquiry in distinct student populations

FEBS Open Bio, EarlyView.
This study addressed how a senior research thesis is perceived by undergraduate students. It assessed students' perception of research skills, epistemological beliefs, and career goals in Biochemistry (science) and BDC (science‐business) students. Completing a thesis improved confidence in research skills, resilience, scientific identity, closed gender‐

The photoswitchable cannabinoid azo‐HU308 enables optical control of Ca2+ dynamics in INS‐1 β‐cells via off‐target effects on TRPC channels

FEBS Open Bio, EarlyView.
Light activation of the photoswitchable cannabinoid ligand azo‐HU308 triggers Ca2+ influx in pancreatic β‐cells through TRPC channels, independent of CB2 cannabinoid receptors. This reveals a non‐GPCR pathway for cannabinoid modulation of β‐cell Ca2+ dynamics and establishes azo‐HU308 as an optical tool to study cannabinoid signaling through TRP ...

Durian fruit pulp extract enhances intracellular glutathione levels, mitigating oxidative stress and inflammation for neuroprotection

Scientific Reports
Durian (Durio zibethinus L.) fruit pulp is a rich source of γ-glutamylcysteine (γ-EC), a direct precursor to the antioxidant glutathione (GSH). This study elucidated the in vitro neuroprotective potential of unripe durian fruit pulp extract (UDE) against

A theory for the tissue specificity of BRCA1/2 related and other hereditary cancers [PDF]

, 2010
Women who inherit a defective BRCA1 or BRCA2 gene have risks for breast and ovarian cancer that are so high and seem so selective that many mutation carriers choose to have prophylactic surgery. There has been much conjecture to explain such apparently

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe

FEBS Open Bio, EarlyView.
Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.
