Abstract
A test station setup devised to measure the emission characteristics and beam propagation parameters of a light detection and ranging (LiDAR) system is presented. The main blocks of the station to measure the accessible emission, wavelength peak and FWHM, pulse duration, pulse repetition rate, horizontal and vertical angular resolution, field of view, beam propagation factor M 2, beam waist size, waist location, and divergence are described. The performance of this test station was demonstrated using a commercial spinning LiDAR, a Velodyne VLP-16, which successfully enables these measurements for a laser beam with a wavelength of 913 nm.

Abstract
Introduction and purpose
Lipodystrophy (LD) syndromes are characterized by the loss of adipose tissue resulting in metabolic complications and accelerated atherosclerosis. The systemic concentration of the adipokine leptin is reduced in LD as a result of adipose tissue deficiency. A therapeutical option to treat LD is the substitution of leptin, which improves metabolic complications and reduces mortality. However, the vascular effects of leptin remain largely unknown.
Here we analyze the direct effects of leptin on the vascular system and the development of atherosclerosis.
Methods and results
Treatment of human endothelial cells (ECs) with leptin reduced endothelial inflammation and the process of endothelial-to-mesenchymal transition (EndMT) (CNN1, −41.4%, p<0.05, n=4). In addition, leptin administration prevented the EndMT-induced increase of endothelial permeability. The protective effect of leptin on EndMT was confirmed in vivo in a combined lipodystrophic and atherosclerosis-prone mouse model (LDLR−/−; aP2-nSrebp1c). Treatment of the mice with leptin (3.0 mg/kg body weight daily for 8 weeks) decreased EndMT. Leptin showed no effect on plaques size but reduced the protrusion of plaques in atherosclerotic areas of the aortic roots (−31%, p<0.05, n=4–6).
Cytokine screening revealed an increase of the growth differentiation factor 15 (GDF15) in serum of LD patients (+26.2%, p<0.05, n=53–58) and in ECs after EndMT (+138%, p<0.05, n=6743–10920). This increase was reversed using leptin treatment in ECs undergoing EndMT, in the LD mice model, and in LD patients after 4 weeks of leptin administration. Indeed, treatment of endothelial cells with GDF15 induced EndMT (CNN1, +7.7-fold-control, p<0.05, n=3), and impaired EC barrier function. Neutralizing antibodies targeting GDF15 inhibited EndMT-mediated expression of mesenchymal genes (CNN1, −54%, p<0.05, n=4). The treatment of ECs with serum from LD patients induced EndMT and the increase of mesenchymal marker expression was inhibited with additional administration with neutralizing antibodies targeting GDF15 (CNN1, −28%, p<0.05, n=3).
Conclusion
Our findings indicate that EndMT is part of the cardiovascular disease progression in lipodystrophy syndromes. Leptin treatment has direct protective vascular effects by preventing inflammation, EndMT, and maintaining endothelial integrity.

Abstract
Norovirus (NoV) is the second most important cause of viral diarrheal disease in children worldwide after rotavirus and is estimated to be responsible for 17% of acute diarrhea in low-income countries. This study aimed to identify and report NoV genotypes in Mozambican children under the age of five years with acute diarrhea. Between May 2014 and December 2015, stool specimens were collected within the Mozambique Diarrhea National Surveillance (ViNaDia) and tested for NoV genogroups I (GI) and II (GII) using conventional reverse transcriptase-polymerase chain reaction (RT-PCR). Partial capsid and RNA-dependent RNA polymerase (RdRp) nucleotide sequences were aligned using the Muscle tool, and phylogenetic analyses were performed using MEGA X. A total of 204 stool specimens were tested for NoV. The detection rate of NoV was 14.2% (29/204). The presence of NoV was confirmed, by real-time RT-PCR (RT-qPCR), in 24/29 (82.8%) specimens, and NoV GII predominated (70.8%; 17/24). NoV GII.4 Sydney 2012[P31] was the predominant genotype/P-type combination detected (30.4%; 7/23). This is the first study which highlights the high genetic diversity of NoV in Mozambican children and the need to establish a continuous NoV surveillance system.

Effects of cathodal transcranial direct current stimulation on hip range of motion of healthy sedentary women: A crossover study. Neurosci Lett 2022; 788:136843.

Abstract
The improvements in range of motion (ROM) by cathodal transcranial direct current stimulation (c-tDCS) were only found in sedentary men and not in females. Thus, the study investigated the effect of c-tDCS on hip flexion range of motion (HFROM) in sedentary women. Ten healthy (27.2 ± 6.4 years for age, 67.9 ± 17.8 kg for body mass, 159.1 ± 7.1 cm for height, and 87.1 ± 3.3° for HFROM) and right-leg-dominant women performed a counterbalanced crossover design in two experimental sessions, separated a week apart: c-tDCS and placebo stimulus (sham). Before and after experimental conditions (Pre-stimulation, Post-stimulation), participants had their HFROM measured. A significant interaction was demonstrated for conditions × time (F(1, 9) = 10.666; ƞ2 = 0.542; p = 0.01), indicating an increase in HFROM in the post-condition (89.0 ± 2.6°) compared to pre-condition (86.5° ± 2.9°) only in the c-tDCS. However, the HFROM improvements varied from 0.3 % to 6.5 % following c-tDCS. This study suggests that c-tDCS applied over the sensorimotor cortex of healthy sedentary women can acutely improve HFROM, but with a low percentage increase.

Abstract
Background On 9 January 2015, in a rural town in Mozambique, >230 persons became sick and 75 died of an illness linked to drinking pombe, a traditional alcoholic beverage. Methods An investigation was conducted to identify case patients and determine the cause of the outbreak. A case patient was defined as any resident of Chitima who developed any new or unexplained neurologic, gastrointestinal, or cardiovascular symptom from 9 January at 6:00 am through 12 January at 11:59 pm. We conducted medical record reviews, healthcare worker and community surveys, anthropologic and toxicologic investigations of local medicinal plants and commercial pesticides, and laboratory testing of the suspect and control pombe. Results We identified 234 case patients; 75 (32%) died and 159 recovered. Overall, 61% of case patients were female (n = 142), and ages ranged from 1 to 87 years (median, 30 years). Signs and symptoms included abdominal pain, diarrhea, vomiting, and generalized malaise. Death was preceded by psychomotor agitation and abnormal posturing. The median interval from pombe consumption to symptom onset was 16 hours. Toxic levels of bongkrekic acid (BA) were detected in the suspect pombe but not the control pombe. Burkholderia gladioli pathovar cocovenenans, the bacteria that produces BA, was detected in the flour used to make the pombe. Conclusions We report for the first time an outbreak of a highly lethal illness linked to BA, a deadly food-borne toxin in Africa. Given that no previous outbreaks have been recognized outside Asia, our investigation suggests that BA might be an unrecognized cause of toxic outbreaks globally.

Abstract
RESUMO A cicatrização de feridas é um processo que requer a interação de várias células da derme e epiderme. O objetivo deste trabalho foi avaliar qual o momento da aplicação das células das ADSCs em feridas cutâneas agudas que faria diferença na cicatrização nos primeiros sete dias da lesão. As células-tronco foram isoladas do tecido adiposo de camundongos C57Bl/6 GFP+. Para tanto, foram utilizados 49 camundongos C57Bl/6, divididos em quatro grupos: grupo I (GI/controle; n=14); grupo II (GII; n=14): ADSCs injetadas no d0; grupo III (GIII; n=14): ADSCs injetadas no terceiro dia; e Grupo IV (GIV; n=7): ADSCs injetadas no quinto dia. As avaliações clínicas ocorreram nos dias zero, três, cinco e sete, e as histopatológicas nos dias cinco e sete. Na metodologia proposta, foi observado que o uso de ADSCs aumenta a vascularização, a formação de tecido de granulação, a colagenização e incrementa o número de folículos pilosos em apenas sete dias de avaliação. Além disso, o momento da aplicação das células não repercutiu diferenças significativas nas fases inflamatória e proliferativa do processo de cicatrização das feridas cutâneas.

Abstract
Objectivos: O tratamento consensual na doença articular avançada da metacarpofalângica é a artroplastia com interposição de prótese. O objectivo deste trabalho foi avaliar o resultado das artroplastias de silicone realizadas em mãos reumatóides, no serviço de Ortopedia do Hospital de Santo António, nos últimos 15 anos.
Material e método: foram revistas 124 próteses de 26 doentes operados nos últimos 15 anos, avaliando-os clínica e radiologicamente, com aplicação de escalas e algoritmos de avaliação de dor, função pré e pós operatória, resultado estético e satisfação global.
Resultados: A maioria dos doentes apresentava artrite reumatóide, atingimento bilateral sendo avaliado o follow-up entre 18 meses e 13 anos. A indicação cirúrgica predominante foi a dor seguida e acompanhada pelo défice de função. Utilizou-se a prótese de Swanson em 82% dos doentes, com correcção do desvio cubital associado em 47%. Houve uma recuperação média de 28 graus do arco de mobilidade articular e 4 graus na escala decimal de dor. Registaram-se 10 complicações (seis fracturas e quatro luxações de prótese). A satisfação global dos doentes foi positiva (67%) com melhoria das actividades da vida diária e deformidade das mãos.
Conclusão: A prótese de silicone demonstrou ser uma boa opção de tratamento para a doença articular reumatóide das MCF com excelentes resultados funcionais, estéticos e dor.

Abstract
Background Grading schemes for the assessment of hepatic fibrosis and necroinflammatory activity in humans previously have been applied to dogs with chronic hepatitis. Interobserver agreement is a desirable characteristic for any histological scoring scheme. Hypothesis/Objectives To assess interobserver agreement associated with pathologists using a previously published histological scoring scheme to assess hepatic fibrosis and necroinflammatory activity in dogs and to compare fibrosis scores assigned to serial sections stained with hematoxylin & eosin (H&E) and picrosirius red. Animals Histological sections of liver from 50 dogs with variable degrees of hepatic fibrosis and necroinflammatory activity were selected from institutional tissue archives. Methods Six board‐certified veterinary anatomic pathologists assigned fibrosis and necroinflammatory activity scores to the histological sections. The multiuser kappa statistic was calculated to assess interobserver agreement. Fibrosis stage assigned to serial sections stained with picrosirius red and H&E was compared using the Wilcoxon signed‐rank test. Results Multiuser kappa statistics for assessment of fibrosis and necroinflammatory activity from H&E‐stained sections were 0.35 and 0.16, respectively. There was no difference in median fibrosis scores assigned to serial section stained with H&E and picrosirius red (P = .248). Conclusions and Clinical Importance There was fair interobserver agreement when pathologists assessed fibrosis and poor agreement when they assessed necroinflammatory activity. This suboptimal agreement must be taken into account by clinicians making decisions based on histology reports of the liver and in the design of studies evaluating these findings. To decrease this variability, ideally >1 pathologist should evaluate each section.

Abstract
Genotype-based algorithms that include VKORC1 and CYP2C9 genotypes are less predictive of warfarin dose variability in Africans as opposed to Europeans. Polymorphisms in GGCX, FPGS, or STX1B are associated with warfarin dose requirements in African-Americans. We sought to determine if they influenced warfarin dose in European-Americans, and another African population, specifically Egyptians. We genotyped 529 adults (n = 325 European-Americans, 204 Egyptians) on a stable warfarin dose for GGCX rs12714145 and rs10654848, FPGS rs7856096, and STX1B rs4889606. Rs12714145, rs10654848, and rs7856096 were not associated with warfarin dose, whereas STX1B rs4889606 was a significant determinant in univariate analysis (P < 0.0001) in both cohorts. However, STX1B rs4889606 was in high linkage disequilibrium with VKORC1-1639 G>A, and was no longer significant after including VKORC1-1639 G>A in the regression model. Based on these data, the polymorphisms do not appear to influence, in a clinically important way, warfarin dose requirements in European-Americans and Egyptians.

Abstract
Sexual differentiation in mammals is an event that presents many variations between species. Because it is related to hormonal function, any imbalance in the androgens and estrogens production can lead to malformations. Because sexual differentiation occurs in different ways among various animals, the recognition of their peculiarities becomes important in order to correct reproductive handling in different species. Considering that the guinea pig is commonly used as an experimental model in the reproductive area, the goal of this work was to perform a morphological description of gonad differentiation of the male guinea pig during embryonic development. In total, 11 conceptuses with ages 25 (n = 3), 30 (n = 2), 40 (n = 2), 50 (n = 2), and 65 (n = 2) days were used for light microscopy processing. The embryos at 25 days were processed completely. For the others, the gonads were dissected. The samples were dehydrated in alcohol, embedded in paraffin, and 5-µm sections were stained with hematoxylin-eosin. In the guinea pig gonad at 25 days gestation, there was a presence of gonadal cords, formed by condensation of somatic cells, which is characteristic of an undifferentiated gonad. In addition, we observed the presence of mesonephric and paramesonephric ducts in different embryos, indicating that other genital system organs were not formed. For the 30 days of development of guinea pigs, we observed that gonadal cords were differentiated in testicular cords by invasion of mesenchymal and endothelial cells, and also composed of Sertoli cells and primordial germ cells. These cords were among a large amount of testicular mesenchyme at the 40-day group. With 50- and 65-day development samples, the gonad was completely differentiated into testicle, with the presence of spermatogonia and Sertoli cells in the seminiferous tubules, and a large amount of interstitial Leydig cells around the tubules. We conclude that gonadal differentiation in guinea pig males occurs around the middle of pregnancy, between 25 and 30 days and that, before the end of the pregnancy, at 50 days, the testicle presents morphology similar to that found in the postnatal period.

Abstract
BACKGROUND The aim of this study is to evaluate the role of hyperbaric oxygen in the treatment of diabetic foot ulcers. METHODS We performed a retrospective observational study of all patients with diabetic foot ulcers treated at the Institution's hyperbaric chamber between January 2010 and August 2012. Patient data was obtained upon patient hospital visit and prospective clinical record consultation. RESULTS Twenty-six foot lesions including 13 foot ulcers Wagner grade 2 or greater and 13 amputation stump ulcers were submitted to hyperbaric oxygen therapy between January 2010 and August 2012 in our Institution. Of these, 23 foot lesions completed treatment and complete epithelialization of the primary lesion was achieved in 15 (65%). The mean healing period since the first hyperbaric oxygen therapy session was 16 weeks. Above-ankle amputations were performed in 3 limbs and transmetatarsal amputations in 2 limbs. CONCLUSION Hyperbaric oxygen may be associated with ulcer healing in selected diabetic foot ulcers with impaired cicatrization.

Abstract
BACKGROUND Driving under the influence of multiple substances is a public health concern, but there is little epidemiological data about their combined use and putative impact on driving in low and middle-income countries where traffic crashes have been clustering in recent years. The aim of this study is to estimate the prevalence of alcohol and drug use - as well as their associated factors - among drivers in the context of alcohol outlets (AOs). METHODS A probability three-stage sample survey was conducted in Porto Alegre, Brazil. Individuals who were leaving AO were screened, with the selection of 683 drivers who met the inclusion criteria. Drivers answered a structured interview, were breathalyzed, and had their saliva collected for drug screening. Prevalences were assessed using domain estimation and logistic regression models assessed covariates associated with substance use. FINDINGS Benzodiazepines 3.9% (SE 2.13) and cocaine 3.8% (SE 1.3) were the most frequently detected drugs in saliva. Among drivers who were going to drive, 11% had at least one drug identified by the saliva drug screening, 0.4% two, and 0.1% three drugs in addition to alcohol. In multivariable analyses, having a blood alcohol concentration (BAC)>0.06% was found to be associated with a 3.64 times (CI 95% 1.79-7.39) higher chance of drug detection, compared with interviewees with lower BACs. CONCLUSIONS To drive under the influence of multiple substances is likely to be found in this setting, highlighting an association between harmful patterns of consume of alcohol and the misuse of other substances.

Abstract
It is known that embryos produced in vitro may have structural alterations that often compromise the normal embryo development, generating a high rate of pregnancy loss. The study of these changes is of great importance because it may elucidate the cause of embryonic loss during the first trimester of pregnancy. Thus, the objective of this study was to characterize and compare ultrastructurally bovine blastocysts in the 7th day of development produced by IVF, cloning by somatic cell nuclear transfer (SCNT), and parthenogenesis. In vitro-produced embryos were derived from in vitro-matured oocytes. The somatic cell used to make cloning was fibroblasts of adult cows, and the protocol for parthenogenetic activation of the embryos was done with ionomycin-DMAP. The blastocysts derived from the different experimental groups were fixed in 2.5% glutaraldehyde and processed for transmission electron microscopy evaluation. The results showed that blastocysts derived by SNC and parthenogenesis exhibited a significantly reduced size; the inner cell mass and the blastocoel were not well defined compared with IVF embryos, indicating a less-advanced state of development. Furthermore, organelles of blastocysts derived from SCNT and parthenogenesis were fewer in number and had changes in form, when compared with IVF blastocysts. In parthenogenetic embryos there was the presence of phagosomes, suggesting a high degradation activity of cellular. Mitochondria showed the most significant changes. Although they occur in large quantities in all blastocysts, the morphology of them was impaired in SNC and parthenogenetic embryos (vacuolization, abnormal shape). Such modifications could suggest changes in mitochondria functionality, which may decrease cellular metabolic activity. Thus, we find that the D7 blastocysts derived from SCNT and parthenogenesis showed several ultrastructural differences compared with IVF embryos, with particular reference to a reduced number and morphology of embryo organelles.

Bmoo FIBMP-I: A New Fibrinogenolytic Metalloproteinase from Bothrops moojeni Snake Venom. ISRN TOXICOLOGY 2012; 2012:673941.

Abstract
A new fibrinogenolytic metalloproteinase (Bmoo FIBMP-I) was purified from Bothrops moojeni snake venom. This enzyme was isolated through a combination of three chromatographic steps (ion-exchange, molecular exclusion, and affinity chromatography). Analyses by reverse phase chromatography, followed by mass spectrometry, showed the presence of enzyme isoforms with average molecular mass of 22.8 kDa. The SDS-PAGE analyses showed a single chain of 27.6 kDa, in the presence and absence of reducing agent. The protein has a blocked N-terminal. One of the peptides obtained by enzymatic digestion of a reduced and S-alkylated isoform was completely sequenced by mass spectrometry (MS/MS). Bmoo FIBMP-I showed similarity with hemorrhagic factor and several metalloproteinases (MP). This enzyme degraded Aα-chain faster than the Bβ-chain and did not affect the γ-chain of bovine fibrinogen. The absence of proteolytic activity after treatment with EDTA, together with the observed molecular mass, led us to suggest that Bmoo FIBMP-I is a member of the P-I class of the snake venom MP family. Bmoo FIBMP-I showed pH-dependent proteolytic activity on azocasein, but was devoid of coagulant, defibrinating, or hemorrhagic activities. The kinetic parameters of proteolytic activity in azocasein were determined (V max = 0.4596 Uh(-1)nmol(-1) ± 0.1031 and K m = 14.59 mg/mL ± 4.610).
