The Acute Effects of Aerobic Dance Exercise with and without Face Mask Use on Attention,Perceived Exertion and Mood States

The present study aimed to determine the effect of wearing a face mask during aerobic dance exercise on cognitive function, more specifically on attention, as well as on perceived exertion and mood states. Thirteen healthy college students (9 males and 4 females: mean age = 17.5 years, height = 1.72 m, weight = 71.00 kg) volunteered to participate in this study. They were randomized to perform aerobic dance exercise while wearing a cloth face mask or no mask or a control condition (sitting on a comfortable chair and reading information about the health benefits of aerobic dance exercise) on three separate occasions (with at least one week of interval). Rate of perceived exertion (RPE), the Brunel Mood Scale (BRUMS) and d2 Attention assessment were assessed before and immediately after each condition. The results demonstrated higher concentration performance for the aerobic dance exercise without face mask than the control condition (p = 0.05). Post RPE and BRUMS fatigue subscale values were significantly higher in the aerobic dance exercise with face mask as compared to the aerobic dance exercise without face mask and control condition (all, p < 0.05). BRUMS vigor subscale value significantly differed across conditions (F = 113.84, p < 0.001, ES = 0.86) and was significantly higher in the aerobic dance exercise group without face mask as compared to the aerobic dance exercise with face mask and the control conditions (both, p < 0.001). This study suggests that face mask use during aerobic dance exercise with moderate intensity did not affect attention. Practitioners, students and athletes should avoid wearing face mask while practicing physical activity or aerobic dance exercise with moderate intensity to improve its acute effect on cognitive function.     

Étude ethnobotanique de la flore médicinale dans la commune rurale d’Aguelmouss province de Khénifra (Maroc)

The present study should be set in the framework of valorization of medical plants and traditional knowledge’s from central middle Atlas of Morocco. Using 280 survey forms, hethnobotanical study was conducted during the months of June, July, August and September 2013 on the therapeutic uses of spontaneous medical plants in the seven tribal fractions that compose Aguelmouss municipality; this phase revealed the occurrence of 103 medicinal species which are divided into 43 families and 87 genera. The analyses results showed that six families commonly used by the population with a clear dominance of Lamiaceae. Also, species with very high frequency of use are Thymus willdenowii, Corrigiola telephiifolia Caralluma europaea et Juniperus oxycedrus. Furthermore, leaves are the most used part and the majority of remedies are prepared as a decoction. In terms of the treated disease, disorders of the digestive system ranks first with a rate of 38.9%.     

Short-term aromatase inhibition induces prostatic alterations in adult wistar rat: A biochemical,histopathological and immunohistochemical study

PurposeThis study aimed to evaluate the effects of estrogen reduction on amyloid deposition, some lipid metabolism and oxidative stress markers, PSA-like production and p63 expression in the prostate of the adult rat.MethodsAromatase inhibitor: Formestane (4-OHA), was administrated to male rats, at a dose of 0.1 mg/kg b.w./day, for 10 days. The control group (CONT) received the same volume of placebo injection (NaCl 0.9%).Results4-OHA treatment induced a significant accumulation of intraprostatic cholesterol (138.90 ± 17.64 vs 85.12 ± 2.87, p = 0.01); against an insignificant diminution of malondialdehyde (412.6 ± 54.35 vs 842.70 ± 336.50, p > 0.05) and glutathione (2.40 ± 0.23 vs 3.65 ± 0.88, p > 0.05). This was associated with a significant decrease of nitric oxide (31.76 ± 7.07 vs 179.40 ± 58.35, p = 0.024). Additionally, 4-OHA significantly increased the intraprostatic production of PSA-like (11.12 ± 2.78 vs 3.91 ± 0.43, p = 0.043). The prostatic histology revealed an amyloid deposition, in all prostatic lobes and a smooth muscle layer growth (p < 0.05); especially significant in the dorsal and lateral lobes. Theses lobes manifested a basal cells proliferation, with a 3-fold increase of p63 expression (p < 0.001). The ventral lobe presented epithelial atrophy (37.80 ± 16.20 vs 167.60 ± 5.16, p < 0.05); with occasional and significant proliferative foci (247.00 ± 9.573 vs 167.60 ± 5.16 p < 0.05).Discussion and conclusionAromatase inhibition, in the adult male rat, alters the prostatic function by reducing nitric oxide availability and inducing amyloid deposition along with limiting the differentiation of basal cells, through a lobe-specific p63-overexpression.     

Les lymphomes osseux primitifs au Maroc. Étude rétrospective à propos de 12 cas

Primary bone lymphomas (PBL) are rare. They account for 5% of the primary bone tumors and 1% of the whole of the lymphomas. This is a retrospective study over four years PBL cases gathered at the National Institute of Oncology in Morocco between January 2003 and December 2006. The median age was 44 years; the average time of diagnosis was 11 months. The predominant localization was the lumbar spine. Treatment was based on chemotherapy and radiotherapy. A laminectomy was conducted in the menacing spine localizations. The protocol of chemotherapy used was the CHOP. The follow-up varied, with extremes ranging from 1 month to 3 years. During this follow-up, no relapse was detected. Although the PBL are aggressive tumors, the prognosis is better than other bone tumors.
