Intermediate and Long-Term Outcomes of the Universal 2 Total Wrist Replacement.

 Arthritis of the wrist can lead to severe functionally debilitating pain which, after failed conservative measures, may require treatment with total wrist replacement (TWR). Various prosthetic designs, such as the Universal 2 implant, have been developed in attempts to combat the multitude of complications faced with replacing a complex and highly mobile joint. Having previously published short-term outcome results for the Universal 2 prosthesis, we now present the long-term survival data.

Combination of miR-99b-5p and Enzalutamide or Abiraterone Synergizes the Suppression of EMT-Mediated Metastasis in Prostate Cancer.

Prostate cancer (PCa) is the most frequently diagnosed cancer and second leading cause of cancer deaths among American men. Androgen deprivation therapy (ADT) has been systemically applied as a first-line therapy for PCa patients. Despite the initial responses, the majority of patients under ADT eventually experienced tumor progression to castration-resistant prostate cancer (CRPC), further leading to tumor metastasis to distant organs.

Organoids: An Emerging Precision Medicine Model for Prostate Cancer Research.

Prostate cancer (PCa) has been known as the most prevalent cancer disease and the second leading cause of cancer mortality in men almost all over the globe. There is an urgent need for establishment of PCa models that can recapitulate the progress of genomic landscapes and molecular alterations during development and progression of this disease. Notably, several organoid models have been developed for assessing the complex interaction between PCa and its surrounding microenvironment.

Identification of potential phytochemicals and their inhibitory effect on the PERK receptor mediated UPR pathway for neuronal disease regulation: an insight.

The endoplasmic reticulum (ER) has been considered as the key site of protein biosynthesis and maturation in the eukaryotic cell. In recent years, the sequence at the N-terminal region of translated protein has shown a particular emphasis as a signal responsible for site-specific translocation mediated by post-translational modification. Once the native conformation is not achieved, the degradation pathway is activated, and therefore the restoration of the homeostasis of ER function in UPR pathway is initiated.

Data were collected from 70 CABG patients and 25 age-matched controls.

The multifactorial role of vanillin in amelioration of aluminium chloride and D-galactose induced Alzheimer's disease in mice.

The onset and progression of Alzheimer's disease (AD) are influenced by a variety of factors. These include oxidative stress, overexpression of acetylcholinesterase (AChE), depletion of acetylcholine levels, increased beta-secretase mediated conversion of Amyloid Precursor Protein (APP) to Amyloid Beta (Abeta), accumulation of Abeta oligomers, decrease in Brain Derived Neurotrophic factor (BDNF) and accelerated neuronal apoptosis due to elevated levels of caspase-3. The currently available therapeutic approaches are inadequate in affecting these pathological processes except maybe the overexpression of AChE (AChE inhibitors like donepezil, rivastigmine).

Consequential Impact of Particulate Matter Linked Inter-Fibrillar Mitochondrial Dysfunction in Rat Myocardium Subjected to Ischemia Reperfusion Injury.

A previous study has reported that exposure to PM from diesel exhaust (diesel particulate matter (DPM)) for 21 days can deteriorate the cardiac recovery from myocardial ischemia reperfusion injury (IR), where the latter is facilitated by the efficiency of mitochondrial subpopulations. Many investigators have demonstrated that IR impact on cardiac mitochondrial subpopulations is distinct. In the present study, we decipher the role of PM on IR associated mitochondrial dysfunction at the subpopulation level by administrating PM directly to isolated female rat hearts via KH buffer.

phytochemicals possess SARS-CoV-2 RdRp and human TMPRSS2 protein binding potential.

Abstract: Coronavirus disease-19 (COVID-19) pandemic caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has infected approximately 26 million people and caused more than 6 million deaths globally. Spike (S)-protein on the outer surface of the virus uses human trans-membrane serine protease-2 (TMPRSS2) to gain entry into the cell. Recent reports indicate that human dipeptidyl peptidase-4 inhibitors (DPP4 or CD26) could also be utilized to check the S-protein mediated viral entry into COVID-19 patients.

Cellular and Molecular Machinery of Neuropathic Pain: an Emerging Insight.

Compression neuropathies of the forearm: anatomy, clinical features and management.

The upper limb consists of four major parts: a girdle formed by the clavicle and scapula, the arm, the forearm and the hand. Peripheral nerve lesions of the upper limb are divided into lesions of the brachial plexus or the nerves arising from it. Lesions of the nerves arising from the brachial plexus are further divided into upper (proximal) or lower (distal) lesions based on their location.
