Abstract
INTRODUCTION Alzheimer's disease (AD) is characterized by progressive cognitive decline and a reduction in hippocampal neurotrophins, in which trimethytin (TMT) infusion causes tangles and neuronal dysfunction, creating an AD-like model in rats. Previous studies have demonstrated that crocin, which has anti-inflammatory properties, can enhance learning, memory acquisition, and cognitive behavior. This study aimed to assess the combined impact of aerobic exercise and crocin on memory, learning, and hippocampal Tau and neurotrophins gene expression in AD-like model rats. METHODS Forty male Sprague Dawley rats were randomly divided into five groups: (1) healthy control, (2) Alzheimer's control, (3) endurance training, (4) crocin consumption, and (5) endurance training + crocin. Alzheimer's induction was achieved in groups 2-5 through intraperitoneal injection of 8 mg/kg TMT. Rats in groups 3 and 5 engaged in treadmill running three sessions per week, 15-30 min per session, at a speed of 15-20 m/min for eight weeks, and groups 4 and 5 received daily crocin supplementation of 25 mg/kg. RESULTS Alzheimer's induction with TMT showed significant reduction in memory, learning, NGF, BDNF, and TrkB gene expression, and increase in tau gene expression (all p < 0.05). Notably, endurance training and crocin consumption separately significantly increased memory, learning, NGF, BDNF, and TrkB gene expression while significantly decreasing tau gene expression (all p < 0.05). Importantly, combined endurance training with crocin yielded the most profound effects on memory (p = 0.001), NGF (p = 0.002), BDNF (p = 0.001), and TrkB (p = 0.003) gene expression (p < 0.005), as well as a reduction in tau gene expression (p = 0.001). CONCLUSION These findings underscore the possible impact of endurance training, particularly when coupled with crocin, on enhancing memory, learning, and neurotrophin gene expression and reducing tau gene expression in Alzheimer's rats. These results highlight the possibility of synergistic interventions for improved therapeutic outcomes.

Abstract
INTRODUCTION Tele-exercise training has improved mental and physical health and quality of life (QOL) in people with multiple sclerosis (PwMS), but there is little known about the comparability of effects across modalities and clinical disease courses. OBJECTIVE To evaluate the effect of tele-Pilates and tele-yoga training on physical and mental factors and QOL in PwMS, with a focus on two phenotype classifications - relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS). METHODS Eighty-two persons with RRMS (n = 48) and SPMS (n = 34) were randomly assigned into tele-Pilates (n = 29), tele-yoga (n = 26), or control (n = 27). The tele-exercis training was conducted three times per week for eight weeks. RESULTS Significant time × group interactions were observed for QoL (p = 0.01), physical activity levels (p < 0.001), mental health (p = 0.05), and a decline in depression (p = 0.002) following tele-Pilates and tele-yoga. The corresponding subfactors, including pain, energy, emotional well-being, and role limitation due to emotional and physical problems, have shown significant improvements after interventions compared with control (all p < 0.05). The effects of exercise over control did not depend on MS phenotype (all p > 0.05). DISCUSSION Tele-yoga and tele-Pilates exercises improved QoL and mental and physical health in PwMS, and the benefits were similar across both MS phenotypes. These findings highlight the potential of implementing tele-yoga and tele-Pilates as non-pharmacological mind-body symptomatic treatments for individuals with both RRMS and SPMS.

Abstract
Itch is a sensation defined as the urge to scratch. The central mechanisms of itch are being increasingly studied. These studies are usually based on experimental itch induction methods, which can be classified into the following categories: histamine-induced, induction by other non-histamine chemicals (e.g. cowhage), physically induced (e.g. electrical) and mentally induced (e.g. audio-visual). Because pain has been more extensively studied, some extrapolations to itch can be proposed and verified by experiments. Recent studies suggest that the itch-processing network in the brain could be disrupted in certain diseases. This disruption could be related to the implication of new regions or the exclusion of already engaged brain regions from itch-processing network in the brain.

Abstract
BACKGROUND Despite the prevalence of psoriasis, the processing of itch in psoriasis and its impact on the central nervous system (CNS) remain unclear. OBJECTIVE We studied the influence of psoriasis on the CNS using magnetic resonance imaging techniques (fMRI and DTI, respectively) to investigate whether mentally induced itch can modify the functional connectivity or the white matter microstructure of the brain. METHODS Fourteen patients with chronic psoriasis and 15 healthy controls were recruited. Itch was mentally induced in subjects by videos showing others scratching themselves. RESULTS The observation of functional connectivity during the viewing the video revealed an interconnected network of brain regions that are more strongly coupled in psoriasis patients than in healthy controls. This network links the cerebellum, the thalami, the anteroposterior cingulum, the inferior parietal lobules, the middle temporal poles and the parahippocampal, hippocampal, lingual and supramarginal gyri. We also found connections with the right precuneus and both left insula and superior temporal gyrus. The DTI analysis showed that chronic itch affects the microstructure of white matter, including the anterior thalamic radiations, the superior and inferior longitudinal fasciculi, the corticospinal tracts, the cingulum, the external capsules, the inferior frontal-occipital fasciculi and both minor and major forceps. CONCLUSION Our results indicate that there could exist a network which is more interconnected in psoriasis patients. Among two building blocks of this network, the subnetwork encoding the perception and control of itch sensation is more affected than the subnetwork representing mentalizing and empathy. With an approach consisting of measuring microstructural changes at a local level in the brain, we also contradict the findings obtained with global measures which stated that chronic psoriasis cannot alter the anatomy of the brain. This confirms that itchy pathophysiological conditions have similar effects on functional and structural connectivity as those observed in chronic pain.

Abstract
The effect of 8 weeks yoga training on cortisol and Adrenocorticotropic hormone (ACTH) levels in female patients with Multiple Sclerosis (MS) is examined. Twenty four MS female patients with Expanded Disability Status Scale (EDSS) 1 to 5.5 participated in this study as the subject. The participants were divided into control (n = 10) or training group (n = 14) randomly. Training group performed 90 min yoga training per session, 3 days a week for 8 weeks. Assessments include body composition measurement and blood sampling 48 h before first session and 48 h after the intervention. The results demonstrated that ACTH increased and cortisol decreased compared to the control group (P < 0.05); In conclusion, it seems that yoga training modulates ACTH level in concomitant with reduction in cortisol level in female patients with MS.

Abstract
OBJECTIVES To investigate the effect of silymarin and milk thistle extract on the progression of diabetic nephropathy (DN) in rats. METHODS Diabetes was induced with a single intraperitoneal (IP) injection of streptozotocin (STZ) (60 mg/kg). Silymarin (100 mg/kg/d) or the extract (1.2 g/kg/d) was gavaged for 4 weeks. Blood glucose (BS), serum urea (S(u)), serum creatinine (S(cr)), and 24-h urine protein (Up) were measured and glomerular filtration rate (GFR) was calculated. Concentration of thiobarbituric acid reactive species (TBARS) and activities of glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT) were evaluated in the renal tissue. RESULTS Data were expressed as mean +/- SEM. Silymarin or the extract had no significant effect on BS, S(cr), and GFR. Both milk thistle extract and silymarin, respectively, decreased S(u) (mg/dL) (87.1 +/- 7.78, p < 0.001; 84.5 +/- 7.15, p < 0.001), Up (mg) (5.22 +/- 1.56, p = 0.014; 5.67 +/- 0.86, p = 0.034), and tissue TBARS (nmol/mg protein) (0.67 +/- 0.04, p < 0.001; 0.63 +/- 0.07, p < 0.001) in diabetic rats, compared to diabetic control (DC) (S(u): 131.0 +/- 4.55, Up: 8.3 +/- 0.84, TBARS: 0.94 +/- 0.06). Both the extract and silymarin could increase the activity of CAT (IU/mg protein) (25.5 +/- 4.0, p = 0.005; 20 +/- 1.8, p = 0.16) and GPx (IU/mg protein) (0.86 +/- 0.05, p = 0.005; 0.74 +/- 0.04, p = 0.10), respectively, in diabetic rats compared to DC (CAT = 14.4 +/- 2.0, GPx = 0.57 +/- 0.02). CONCLUSION Milk thistle extract, to a lesser extent silymarin, can attenuate DN in rats possibly by increasing kidney CAT and GPx activity and decreasing lipid peroxidation in renal tissue.

Abstract
The dynamic 1H NMR study of some primary carbamates in the solvents CDCl3 and CD3COCD3 between 183 and 298 K is reported. The free energies of activation, thus obtained (12.4 to 14.3 kcal mol-1), were attributed to the conformational isomerization about the N-C bond. These barriers to rotation show solvent dependence in contrast to the tertiary analogues and are lower in free energy by ca. 2-3 kcal mol-1.
