In this paper, the generalized oscillator strengths (GOSs) of excitations of atomic sodium from ground state to 2p63s0 (3p, 4p, 5p, 6p) states, immersed in Debye plasma, were calculated by using wavefunctions which were obtained numerically from the restricted Hartree-Fock (RHF) equation. This RHF equation employs the local density approach for exchange interactions including plasma Debye screening. Theoretical RHF and random phase approximation with exchange (RPAE) velocity calculations have shown that the GOSs for excitations to 3 s0(3 p,4 p,5 p,6 p)depend on the plasma Debye screening effects, as shown by the reduction in the GOS amplitude with decreasing Debye length λD. The agreement between the present RPAE V results for the transitions 3 s→3 s0(3 p,4 p,5 p)and the length calculations of Martínez-Flores was satisfactory. Correlation effects were found quite to be significant in the vicinity of the maxima of the GOS of the 3 s→3 s0(4 p,5 p,6 p)excitations by using the RPAE V approach. We note the poor influence of many electron correlations on the GOS of (3 s→3 p)transition with the same principal quantum number. Finally, we comment that the RPAE V calculations are useful in investigating electron correlation effects on the transition GOS of atomic sodium planted in Debye plasma. The present velocity results also reveal that the 3 s→3 s0(5p, 6p)transition GOSs tend to be delocalized due to more significant screening effects at Debye lengths λD=20and 30 a.u. for excited subshells 5p and 6p, respectively. We report here novel results of GOS for 3 s→3 s06ptransition obtained from different Debye lengths.

A study was made to determine whether HIV-infected patients with prolonged virological control suffer subclinical neurocognitive problems capable of interfering with driving skills, compared with the general population, and to explore the possible existence of differences between those treated with and without efavirenz. Material and Methods: We included 40 patients without history of neoplasm, psychiatric disorders or infections of the central nervous system associated or not to HIV, with stable and effective antiretroviral therapy during at least 48 months. Use was made of the ASDE DRIVER TEST N-845 standardized by the Spanish traffic authorities, and for which data corresponding to the Spanish general population were obtained from the manufacturer of the test battery. The Student t-test was used to compare the different variables with the population standards, and the comparison of proportions Z-statistic was used to determine the proportion of subjects above the accepted limit of normality cutoff point. These analyses were replicated for the two sub-samples (with or without efavirenz therapy), with a 95% confidence level. The SPSS version 15 statistical package and Epidat 3.1 program were used. Results: The scores obtained in the HIV group were significantly poorer in the anticipation speed tests and in one of the multiple reactions test, though better results were obtained in the bimanual visual-motor coordination test. There were no differences in the percentages of patients with scores below the recommended limits. On comparing the treatment subgroups (efavirenz versus protease inhibitor), no differences were recorded in any of the study variables, and the differences with respect to the general population were the same as those described for the global group. Conclusions: Little differences were observed in driving skills in HIV well controlled HIV patients of minor clinical significance, and no differences were found in driving skills between the patients a

TRPA1 are cation channels expressed in sensory neurons and in several other cell types. This channel is specifically activated by ally isothiocyanate (AITC), the pungent component of mustard oil, as well as by other electrophilic compounds. Although TRPA1 expression in central glia has been reported, its subcellular localization and its expression in peripheral glia have not been investigated before. In this paper we report the molecular and functional expression of TRPA1 in rat cortical astrocytes. Real-time RT-PCR identified low but significant amounts of TRPA1 mRNA in cortical astrocytes while no signal was seen in peripheral glia isolated from dorsal root ganglia (DRG) or in a glial cell line (DITNC-1). Calcium imaging showed AITC-induced signals in astro-cytes while no response in peripheral glia. AITC induced calcium signals in astrocytes in the presence and in the absence of extracellular calcium, suggesting an intracellular localization of TRPA1 channels. Whole cell electrophysiological recordings were performed in astrocytes, in peripheral glia and in DITNC-1 cells transfected with TRPA1 during AITC application. In TRPA1-transfected DITNC-1 cells typical TRPA1 currents were recorded with a reversal potential near 0 mV, consistent with the opening of a non-selective cation channel. No such currents were recorded in untransfected DITNC-1 cells, in astrocytes and in peripheral glial cells, where even high concentrations of AITC (up to 10 mM) induced no significant outward current. In astrocytes AITC transiently induced an outward rectifying current with the reversal potential near ?90 mV, consistent with K channel activation, likely activated by intracellular release of calcium. Our results suggest that TRPA1 channels are molecularly and functionally expressed in calcium-containing organelles of rat cortical astrocytes, with no expression in the plasma membrane.

A survey on the parasitological and bacteriological management was conducted in two villages in southeastern Senegal. The objective of this study was to evaluate the water management modalities in the two villages with ethnic differences and possibly detect factors that could cause waterborne diseases. A questionnaire on water management methods was submitted to one hundred one women drawn in the villages of Dielmo and Ndiop. Samples of well water and water stored in canaries were subjected to both parasitological and bacteriological analysis. In both villages, there was a difference in water management with respect to household configuration (monogamous, polygamous). The containers used for the drawing and storage of water were the same in their two villages. No helminth eggs were found in the drinking water, but bacterial germs, especially faecal coliforms (an indicator of human contamination) and Enterocoques (an indicator of animal contamination). These waters do not comply with WHO standards. So it is important to disinfect them before consumption although no cases of gastroenteritis have been reported.

Carrier tunnelling through GaAs barriers of different thicknesses is investigated in vertically InGaAs/GaAs quantum rings (QR’s). Shorter PL decay time of the ground state emission of high-energy component in the sample with thicker spacer (1.5 nm) is ascribed to both tunnelling effect between the two QR families and vertical coupling between layers in the stacks. We found that tunnelling time between QR’s followed the Wentzel-Kramers-Brillouin (WKB) approximation. The non resonant tunnelling rate between QR’s is found to be different by one order of magnitude from the rate in quantum dots (QD’s).

Introduction: Non-communicable diseases constitute a major public health problem, due to their morbi-mortality. The aim was to study knowledge of cardiovascular risk factors among residents of Dakar. Patients and Methods: This was a descriptive cross-sectional study. Our investigations were recruited over a six-month period (October 17, 2021 to March 21, 2022). Results: Two hundred and twenty-six (226) patients were enrolled. The mean age was 45.9 years. The under-40 age group was the most represented with 37.2%. There were 129 men (57.1%), giving a male/female sex ratio of 1.33. The highest level was represented by 159 people (70.4%). Those who responded (heart disease) were in the majority (38.1%). Hypertension was the most common CVD for 101 people (44.7%). One hundred and ninety (190) people (84%) knew the risk factors for CVD. Good knowledge of risk factors concerned 103 people (54.2%). Obesity was the best-known risk factor in 156 cases (69%). The media was the most important source of information for 121 people (53.5%). Hypertensives were the most represented with 8.4%. One hundred and thirty (130) people (57.5%) had previously paid attention to these FDRCVs. Awareness campaigns were the most effective means of communication for 170 cases (75.2%). Sixteen (16) people (35.6%) were taking antihypertensive medication. Walking was the most popular physical activity for 102 people (45%). People with a balanced diet were in the majority, with 174 respondents (77.0%). Conclusion: NCDs are a major cause of morbidity and mortality. It is essential to develop and implement a prevention and management program.
