Male accessory gland substances from Aedes albopictus affect the locomotor activity of Aedes aegypti females

Dengue is one of the world’s most important mosquito-borne diseases and is usually transmitted by one of two vector species: Aedes aegypti or Aedes albopictus . These two diurnal mosquitoes are frequently found coexisting in similar habitats, enabling interactions between adults, such as cross-mating. The objective of this study was to assess cross-mating between Ae. aegypti females and Ae. albopictus males under artificial conditions and evaluate the locomotor activity of Ae. aegypti virgin females injected with male accessory gland (MAG) homogenates to infer the physiological and behavioural responses to interspecific mating. After seven days of exposure, 3.3-16% of Ae. aegypti females mated with Ae. albopictus males. Virgin Ae. aegypti females injected with conspecific and heterospecific MAGs showed a general decrease in locomotor activity compared to controls and were refractory to mating with conspecific males. The reduction in diurnal locomotor activity induced by injections of conspecific or heterospecific MAGs is consistent with regulation of female reproductive activities by male substances, which are capable of sterilising female Ae. aegypti through satyrisation by Ae. albopictus .

Influences of β-HCG administration on carbon isotope ratios of endogenous urinary steroids.

Several factors influencing the carbon isotope ratios (CIR) of endogenous urinary steroids have been identified in recent years. One of these should be the metabolism of steroids inside the body involving numerous different enzymes. A detailed look at this metabolism taking into account differences found between steroids excreted as glucuronides or as sulphates and hydrogen isotope ratios of different steroids pointed out possibility of unequal CIR at the main production sites inside the male body - the testes and the adrenal glands. By administration of β-HCG it is possible to strongly stimulate the steroid production within the testes without influencing the production at the adrenal glands. Therefore, this treatment should result in changed CIR of urinary androgens in contrast to the undisturbed pre-treatment values. Four male volunteers received three injections of β-HCG over a time course of 5 days and collected their urine samples at defined intervals after the last administration. Those samples showing the largest response in contrast to the pre-administration urines were identified by steroid profile measurements and subsequent analysed by GC/C/IRMS. CIR of androsterone, etiocholanolone, testosterone, 5α- and 5β-androstanediol and pregnanediol were compared. While pregnanediol was not influenced, most of the investigated androgens showed depleted values after treatment. The majority of differences were found to be statistically significant and nearly all showed the expected trend towards more depleted δ(13)C-values. These results support the hypothesis of different CIR at different production sites inside the human body. The impact of these findings on doping control analysis will be discussed.

Comodidad materna y reducción del dolor en mujeres con posición fetal occipitoposterior durante el parto con el uso de las posturas de decúbito lateral y manos-rodillas: Ensayo clínico aleatorizado

Objective: To assess the maternal comfort and reduction of pain associated with contractions during labor with “hands-knees” (HK) maternal posture compared with “lateral maternal postures toward the fetal back” in pregnant women with occipitoposterior (OP) fetal position. Methods: In the multicenter trial by randomization, 70 women with OP fetal position during labor took the lateral posture and 65 women the HK posture for at least 30 minutes. We analyzed maternal comfort, perceived pain, influence of epidural analgesia and use of fit-ball on posture HK. Results: Back pain and abdominal pain reduction was higher with HK posture. With lateral posture 78.6% of women expressed comfort versus 73.8% of women with HK posture. Regarding the lateral posture, the comfort with HK posture reduces in multiparous women, with an odds ratio (OR) of 0.29, for a confidence interval (CI) 95% 0.12 to 0.76, and epidural analgesia (OR= 0.39; CI 95%: 0.15-1.03), comfort with K posture is higher with reduction of pain (OR= 4.13, 95% CI: 1.34- 12.72) and abdominal pain compared with back pain (OR= 4.05, 95% CI: 1.36-11.85). Conclusions: Women consider comfortable lateral and HK maternal postures during labor. The lateral posture is most comfortable for multiparous and epidural analgesia. The reduction of pain during labor is higher with HK posture, recommending this posture in primiparous women without epidural analgesia.

Postischemic treatment of neonatal cerebral ischemia should target autophagy.

OBJECTIVE: To evaluate the contributions of autophagic, necrotic, and apoptotic cell death mechanisms after neonatal cerebral ischemia and hence define the most appropriate neuroprotective approach for postischemic therapy. METHODS: Rats were exposed to transient focal cerebral ischemia on postnatal day 12. Some rats were treated by postischemic administration of pan-caspase or autophagy inhibitors. The ischemic brain tissue was studied histologically, biochemically, and ultrastructurally for autophagic, apoptotic, and necrotic markers. RESULTS: Lysosomal and autophagic activities were increased in neurons in the ischemic area from 6 to 24 hours postinjury, as shown by immunohistochemistry against lysosomal-associated membrane protein 1 and cathepsin D, by acid phosphatase histochemistry, by increased expression of autophagosome-specific LC3-II and by punctate LC3 staining. Electron microscopy confirmed the presence of large autolysosomes and putative autophagosomes in neurons. The increases in lysosomal activity and autophagosome formation together demonstrate increased autophagy, which occurred mainly in the border of the lesion, suggesting its involvement in delayed cell death. We also provide evidence for necrosis near the center of the lesion and apoptotic-like cell death in its border, but in nonautophagic cells. Postischemic intracerebroventricular injections of autophagy inhibitor 3-methyladenine strongly reduced the lesion volume (by 46%) even when given >4 hours after the beginning of the ischemia, whereas pan-caspase inhibitors, carbobenzoxy-valyl-alanyl-aspartyl(OMe)-fluoromethylketone and quinoline-val-asp(OMe)-Ch2-O-phenoxy, provided no protection. INTERPRETATION: The prominence of autophagic neuronal death in the ischemic penumbra and the neuroprotective efficacy of postischemic autophagy inhibition indicate that autophagy should be a primary target in the treatment of neonatal cerebral ischemia.

Prospective comparison of MR enteroclysis with multidetector spiral-CT enteroclysis: interobserver agreement and sensitivity by means of "sign-by-sign" correlation.

Our objective was a prospective comparison of MR enteroclysis (MRE) with multidetector spiral-CT enteroclysis (MSCTE). Fifty patients with various suspected small bowel diseases were investigated by MSCTE and MRE. The MSCTE was performed using slices of 2.5 mm, immediately followed by MRE, obtaining T1- and T2-weighted sequences, including gadolinium-enhanced acquisition with fat saturation. Three radiologists independently evaluated MSCTE and MRE searching for 12 pathological signs. Interobserver agreement was calculated. Sensitivities and specificities resulted from comparison with pathological results ( n=29) and patient's clinical evolution ( n=21). Most pathological signs, such as bowel wall thickening (BWT), bowel wall enhancement (BWE) and lymphadenopathy (ADP), showed better interobserver agreement on MSCTE than on MRE (BWT: 0.65 vs 0.48; BWE: 0.51 vs 0.37; ADP: 0.52 vs 0.15). Sensitivity of MSCTE was higher than that of MRE in detecting BWT (88.9 vs 60%), BWE (78.6 vs 55.5%) and ADP (63.8 vs 14.3%). Wilcoxon signed-rank test revealed significantly better sensitivity of MSCTE than that of MRE for each observer ( p=0.028, p=0.046, p=0.028, respectively). Taking the given study design into account, MSCTE provides better sensitivity in detecting lesions of the small bowel than MRE, with higher interobserver agreement.

Inoculum effect on the efficacies of amoxicillin-clavulanate, piperacillin-tazobactam, and imipenem against extended-spectrum β-lactamase (ESBL)-producing and non-ESBL-producing Escherichia coli in an experimental murine sepsis model.

Escherichia coli is commonly involved in infections with a heavy bacterial burden. Piperacillin-tazobactam and carbapenems are among the recommended empirical treatments for health care-associated complicated intra-abdominal infections. In contrast to amoxicillin-clavulanate, both have reduced in vitro activity in the presence of high concentrations of extended-spectrum β-lactamase (ESBL)-producing and non-ESBL-producing E. coli bacteria. Our goal was to compare the efficacy of these antimicrobials against different concentrations of two clinical E. coli strains, one an ESBL-producer and the other a non-ESBL-producer, in a murine sepsis model. An experimental sepsis model {~5.5 log10 CFU/g [low inoculum concentration (LI)] or ~7.5 log(10) CFU/g [high inoculum concentration (HI)]} using E. coli strains ATCC 25922 (non-ESBL producer) and Ec1062 (CTX-M-14 producer), which are susceptible to the three antimicrobials, was used. Amoxicillin-clavulanate (50/12.5 mg/kg given intramuscularly [i.m.]), piperacillin-tazobactam (25/3.125 mg/kg given intraperitoneally [i.p.]), and imipenem (30 mg/kg i.m.) were used. Piperacillin-tazobactam and imipenem reduced spleen ATCC 25922 strain concentrations (-2.53 and -2.14 log10 CFU/g [P < 0.05, respectively]) in the HI versus LI groups, while amoxicillin-clavulanate maintained its efficacy (-1.01 log10 CFU/g [no statistically significant difference]). Regarding the Ec1062 strain, the antimicrobials showed lower efficacy in the HI than in the LI groups: -0.73, -1.89, and -1.62 log10 CFU/g (P < 0.05, for piperacillin-tazobactam, imipenem, and amoxicillin-clavulanate, respectively, although imipenem and amoxicillin-clavulanate were more efficacious than piperacillin-tazobactam). An adapted imipenem treatment (based on the time for which the serum drug concentration remained above the MIC obtained with a HI of the ATCC 25922 strain) improved its efficacy to -1.67 log10 CFU/g (P < 0.05). These results suggest that amoxicillin-clavulanate could be an alternative to imipenem treatment of infections caused by ESBL- and non-ESBL-producing E. coli strains in patients with therapeutic failure with piperacillin-tazobactam.

Age-Related Macular Degeneration: Clinical Findings following Treatment with Antiangiogenic Drugs.

Purpose. To survey the management of patients with neovascular age-related macular degeneration (nvAMD) in Spain. Methods. An observational retrospective multicenter study was conducted. The variables analyzed were sociodemographic characteristics, foveal and macular thickness, visual acuity (VA), type of treatment, number of injections, and the initial administration of a loading dose of an antiangiogenic drug. Results. 208 patients were followed up during 23.4 months in average. During the first and second years, patients received a mean of 4.5 ± 1.8 and 1.6 ± 2.1 injections of antiangiogenic drugs, and 5.4 ± 2.8 and 3.6 ± 2.2 follow-up visits were performed, respectively. The highest improvement in VA was observed at 3 months of follow-up, followed by a decrease in the response that stabilized above baseline values until the end of the study. Patients who received an initial loading dose presented greater VA gains than those without. Conclusions. Our results suggest the need for a more standardized approach in the management and diagnosis of nvAMD receiving VEGF inhibitors. To achieve the visual outcomes reported in pivotal trials, an early diagnosis, proactive approach (more treating than follow-up visits), and a close monitoring might be the key to successfully manage nvAMD.
