Article Abstract
Molecular motor proteins are an extremely important component of the cellular transport system that harness chemical energy derived from ATP hydrolysis to carry out directed mechanical motion inside the cells. Transport properties of these motors such as processivity, velocity, and their load dependence have been well established through single-molecule experiments. Temperature dependent biophysical properties of molecular motors are now being probed using single-molecule experiments. Additionally, the temperature dependent biochemical properties of motors (ATPase activity) are probed to understand the underlying mechanisms and their possible implications on the enzymatic activity of motor proteins. These experiments in turn have revealed their activation energies and how they compare with the thermal energy available from the surrounding medium. In this review, we summarize such temperature dependent biophysical and biochemical properties of linear and rotary motor proteins and their implications for collective function during intracellular transport and cellular movement, respectively.

Alzheimer's disease (AD) is the most common, complex, and untreatable form of dementia which is characterized by severe cognitive, motor, neuropsychiatric, and behavioural impairments. These symptoms severely reduce the quality of life for patients and impose a significant burden on caregivers. The existing therapies offer only symptomatic relief without addressing the underlying silent pathological progression.

Introduction: Spinal muscular atrophy (SMA), caused by pathogenic variants in the survival motor neuron (SMN) gene, is the most common genetic cause of mortality in children under the age of two. Prior reports of obstetric sonograms performed in pregnancies with severe forms of fetal SMA have discrepant findings that may stem from a failure to account for the SMN2 copy number.
Methods: We present a neonate diagnosed with SMA type 0 postnatally (0SMN1/1SMN2 genotype).

Background And Purpose: Parkinson's disease (PD), a prevalent neurodegenerative disorder characterized by motor impairments, frequently accompanied by neuropsychiatric symptoms that significantly impair daily functioning and quality of life. The present study aimed to assess the efficacy of botulinum toxin A (BTX-A) in alleviating neuropsychiatric symptoms among PD patients.
Methods: This is an open-label, nonrandomized controlled trial.
Maturation of Micturition-Related Neural Circuits That Control Pelvic Visceromotor Functions in Postnatal Rats.

Pelvic visceromotor functions such as micturition are regulated by coordinated autonomic and somatic motor pathways from the central nervous system. The parasympathetic system induces detrusor muscle contraction while the somatic system facilitates relaxation of the external urethral sphincter, ensuring synchronized and efficient bladder emptying during the voiding process. This study explores the relationship between Barrington's nucleus corticotropin-releasing hormone (CRH)-ergic projections and the formation of perineural nets (PNNs) among spinal motoneurons, particularly parasympathetic preganglionic neurons in the intermediolateral nucleus (IML) and Onuf's nucleus during the maturation of the neural circuitry controlling pelvic visceromotor functions.

Acute or chronic liver damage can result in Hepatic Encephalopathy (HE), a potentially fatal neuropsychiatric condition that leads to cerebral and neurological alterations. Dapagliflozin (DAPA), an orally active Sodium/Glucose cotransporter 2 inhibitor with long duration of action. The study aim was to evaluate the potential protective impact of DAPA against HE caused by Thioacetamide (TAA) in rats.
