Published: May 2022

The purpose of the present study was to identify integrons and gene cassettes in vibrios isolated from the hemolymph of shrimp (Litopenaeus vannamei) farmed in Ceará (Northeastern Brazil). Twenty-five vibrio strains were evaluated on PCR for class 1 integrons in chromosomal and plasmidial DNA, using the primers In, Int1, qacE∆1, sul1 and blaP1. Eight (32%) isolates yielded integrase (intI1) in chromosomal DNA belonging to class 1 integrons, with the gene cassette blaP1 detected in strains of V. natriengens (V10), V. coralliilyticus (V11) and V. parahaemolyticus (V25). The percentage was 100% in plasmids, with the detection of the gene cassettes blaP1 and ereA2 in V. vulnificus B1 (V4), V. coralliilyticus (V7), V. alginolyticus (V8), V. harveyi (V9), V. alginolyticus (V16), V. harveyi (V18), V. parahaemolyticus (V19), V. parahaemolyticus (V21) and V. mimicus (V22). The detection of antimicrobial resistance gene cassettes in the isolated strains indicates the possibility of dissemination of these genetic elements to autochthonous bacteria in shrimp culture environment.

METHODS OF SEX ESTIMATION FROM THE CLAVICLES IN FORENSIC EXAMINATION OF BONE REMAINS
Authors: Smirnov Askold , Sundukov Dmitriy
Published: May 2022

One of the most complex problems in forensic medical expertise is the process of identification of unknown corpses and their parts, which very often include bone remains. Sometimes it is practically impossible to collect the data needed for police investigation because the most important parts of the skeleton such as skull, pelvic bones and long trabecular bones are absent. The aim of the study was to develop new methods for sex determination from the clavicle of an adult person based on the mathematical and statistical analysis of their osteometric properties. For this purpose bone samples from three skeletal collections were used: collection of the Department of Anthropology of Lomonosov Moscow State University; collection of the Department of Physical Anthropology of the Peter the Great Museum of Anthropology and Ethnography (St. Petersburg), and the The Robert J. Terry Anatomical Skeletal Collection stored at the Department of Physical Anthropology of the Smithsonian’s National Museum of Natural History (Washington). The study demonstrated the possibility of correct sex determination from the clavicle using the five-interval diagnostic table suitable for quick sex assessment and multiple discriminant models with an accuracy of correct sex estimation between 85% and 97.5%. The methods described in the article can be applied not only in forensic context (especially when working with a limited set of isolated skeletal elements or their fragments), but also in the physical and medical anthropology for reconstructing an unidentified individual’s biological profile.

Published: May 2022

Diagnosis of terminal conditions is an important field of forensic medicine. When shock occurs all human physiological functions are replaced with pathological processes, including development of disseminated intravascular coagulation (DIC) syndrome, develop. In DIC syndrome two opposite processes, such as increased blood clotting and activation of the fibrinolytic system, take place. This paper provides information on post-mortal diagnosis of DIC syndrome for anaphylactic and other types of shock. The quantitative content of the fibrinogen fraction and the results of paracoagulation tests allow post-mortem diagnosis of DIC syndrome and identification of the process stage. These studies indicate shock at the time of death and are especially relevant for post-mortem diagnosis of anaphylactic and other types of shock.

Aim: to study the effectiveness of different treatment options for male hypogonadism. Material and methods: the paper investigates outcomes in treating male hypogonadism (86 patients with secondary male hypogonadism). Scientific literature was reviewed to single out the following methods: androgen replacement therapy subcutaneous testosterone pellet implants use of long-acting subcutaneous testosterone tablets (the use of subcutaneous long-acting testosterone tablets as replacement therapy), a combination of traction therapy and medication Testosterone undecanoate. Results: androgen replacement therapy promotes the development of a number of beneficial effects in terms of physique, metabolic control, psychological and sexual indicators. The use of long-acting subcutaneous testosterone pellets can enhance the androgenic effect at the receptor level. The combined method of treatment traction therapy and medication Testosterone undecanoate is relevant for men with concomitant micropenia. The surgical method of subcutaneous testosterone pellet implants is recommended for patients with contraindications to testosterone replacement therapy. The determination of sexual constitution’s indicators testified to persistent sexual rehabilitation in the long term after transplantation of testicle. Conclusions: Each clinical case should be approached individually and optimized in case of concomitant pathologies. According to the scientific literature, androgen replacement therapy is optimized as an application of long-acting subcutaneous testosterone tablets, which shows good results in case of concomitant pathologies. For men with concomitant micropenia, it is suggested to apply the combined treatment of traction therapy and medication Testosterone undecanoate. In case of contraindication to hormone therapy, subcutaneous testosterone pellet implants are the optimal option.

Published: May 2022

Introduction. Despite the ample prevalence of antimony in the human environment, there are still no reliable data on its nephrotoxicity. Data from the literature are inconsistent. Materials and methods. The experiments were performed in 2 groups of male Wistar rats weighing 200-250 g. Group 1: intact animals; Group 2: animals with intragastric injection of antimony chloride solution. The solution was injected through a probe into the stomach every day at a dose of 3 mg/kg for one and two months. After the experiment was terminated, the rats were euthanised under thiopental anaesthesia for plasma and renal tissue examination. The basic processes of urine formation, blood electrolyte content (sodium, potassium and calcium) and kidney function were studied under conditions of spontaneous 6-hour diuresis after one and two months. Content of sodium and potassium in biological material was determined by ion-selective method on electrolyte analyzer AEK-1 (Kverti-Med). The concentration of calcium and creatinine in urine and blood plasma, total protein in urine were determined spectrophotometrically. For histological studies, kidney tissue samples were fixed in 10% neutral formalin, then embedded in paraffin, followed by preparation of 7-8 microns thick sections. The sections were stained with hematoxylin and eosin. The sections were studied in transmitted light using a Mikmed-1 microscope at a magnification of 80x200x400. Results. Experiments showed that chronic sulimic intoxication leads to toxic nephropathy, manifested after 2 months of intoxication by a sharp decrease in diuresis due to decreased glomerular filtration rate, impaired electrolyte-excretory function of the kidneys, proteinuria. Morphological examination showed alterative changes: urinary space of glomeruli was enlarged, capillary endothelium with signs of hydropic dystrophy. There was hyaline-drop dystrophy of renal tubule epithelium with partial necrosis. Stroma was edematous, vessels were full of blood with hyalinosis of their walls. Conclusion. Prolonged antimony intoxication leads to nephropathy. Manifestations of the latter after one month and two months of intoxication differ in direction, but are accompanied by marked proteinuria.

To build an analytical model, such parameter as gestational age is used, measured in weeks with the range of changes in the score between 0 to 10, where a score of 38 - 40 weeks should correspond to 0 points, i.e., at this gestational age, the morbidity rate due to morphological immaturity of organs and systems is minimal, because by this gestational age the organ development is almost completed. The maximum score is 9.9, at gestational age of 22 weeks, which is associated with severe morphological immaturity and, therefore, high morbidity in a premature infant. Results. Based on mathematical calculations, we built a model of prematurity score, which helps estimate the degree of abnormality of a premature baby depending on gestational age. The lower it is, the higher is the score of prematurity and the likelihood of morbidity due to morphological immaturity of organs and systems. Conclusion. The proposed analytical model of prematurity score can be used to uniformly assess the prematurity factor in order to further determine the medical strategy. The model can be effectively used in scientific research and to identify statistically necessary relationships in a wide variety of studies. The main value of the model lies not in obtaining specific numerical values, but in the suggested analytical relationship reflecting the degree of morphological maturity and allowing probability estimation of the newborn morbidity.

Diferencias en los ensambles de anfibios y reptiles entre tipos de vegetación en las estribaciones del Cinturón Volcánico Trans-Mexicano en el estado de Michoacán, México

Se presenta información sobre la estructura y distribución de los ensambles herpetofaunísticos en diferentes tipos de vegetación (bosque de pino-encino [PE], selva baja caducifolia [SB], bosque de Sabal (Sabal pumus) [SP] y huertas de aguacate (Persea americana) [HA]). El municipio de Ario de Rosales, Michoacán está localizado en los límites entre el Cinturón Volcánico Trans-Mexicano y la Cuenca del Río Balsas. El muestreo de campo se realizó de agosto de 2009 a noviembre de 2010. Los resultados indicaron diferencias en composición de los ensambles herpetofaunísticos entre los tipos de vegetación. La riqueza total (gama) del paisaje se caracterizó por incluir 54 especies (18 anfibios, 17 serpientes, 16 lagartijas y 3 tortugas). El SB presentó la más alta diversidad alfa (diversidad local), seguido de SP, HA, y PE. Se registró una marcada diferencia en diversidad entre tipos de vegetación. El alto número de especies exclusivas presentes por tipo de vegetación indica baja similitud entre sitios y elevada influencia en la diversidad beta. Las diferencias en la composición entre sitios y el alto número de especies exclusivas sugieren que la herpetofauna presente en cada ambiente la integran especies especificas a cada cobertura vegetal. Adicionalmente, alrededor de 70% de las especies registrada son endémicas a México, 39% están en la Norma Oficial Mexicana consideradas en riesgo a nivel país y ~ 4% están consideradas en riesgo a nivel global.
La crisis ambiental y su efecto sobre los venados de México
Authors: Gallina Tessaro Sonia
Published: May 2022

Actualmente nos estamos percatando que entramos a una crisis ambiental que está teniendo consecuencias negativas sobre las poblaciones de las especies tanto de plantas como de animales, poniendo en riesgo a múltiples poblaciones de las especies, lo que eventualmente podrá llevarlas a la extinción. ¿Por qué la llamamos crisis ambiental? Porque la deforestación, el cambio de uso de suelo y el cambio climático han influido en el aumento de la temperatura a nivel global, lo que está produciendo tanto sequías más prolongadas como lluvias más intensas, modificando de manera el ambiente en el que plantas y animales se desarrollan.
Pondremos como ejemplo el caso de las poblaciones de venados en nuestro país y como pueden verse afectadas con esta crisis ambiental. En México contamos con 4 especies de venados: el venado cola blanca (Odocoileus virginianus) que se distribuye prácticamente en todo el país con excepción de la Península de Baja California, y es una de las especies con un gran valor cinegético y cultural, el venado bura (O. hemionus) que se encuentra en la Península de Baja California y los estados del Noroeste del país, el temazate rojo (Mazama temama) en el Sureste desde Tamaulipas hasta la
Península de Yucatán y el temazate gris (M. pandora) exclusivo de la Península de Yucatán.
Estas especies pueden ser únicamente aprovechadas en México a través de la conversión de los
predios rurales en Unidades de Manejo para la Conservación de la Vida Silvestre (UMA) normadas
y propuestas por SEMARNAP (hoy SEMARNAT Secretaría del Medio ambiente y Recursos Naturales)
desde 1997 y parten de la premisa de conservar y aprovechar sustentablemente la flora y fauna de
forma legal, para obtener beneficios y generar oportunidades en diferentes sectores de la sociedad,
permitiendo a propietarios de tierras ejidales, comunales y privadas, además de representantes,
trabajadores y administradores, tener una visión de apropiación y valorización ecológica, económica
y social, y con ello hacer uso, manejo y aprovechamiento legal de la vida silvestre (Weber et al. 2006,
Sisk et al. 2007, Gallina et al. 2009, Robles de Benito 2009, Servín et al. 2018, SEMARNAT 2019).

Time-resolved photoluminescence and capacitance-voltage measurement were performed on p-type GaN and InGaN films to study the minority carrier recombination mechanism. The minority carrier lifetime (τ
PL) for p-GaN with a Mg concentration of 1.7 × 1019 cm−3 was 46 ps. The non-radiative recombination due to gallium vacancies (V
Ga)-related defects is confirmed to dominate the minority carrier transport process. To suppress the formation of V
Ga defects, the indium atoms were added into p-GaN. As a consequence, the V
Ga-related non-radiative recombination centers were reduced from 8 × 1015 to 5 × 1014 cm−3 and a record long τ
PL of 793 ps was obtained for p-In0.035Ga0.95N film.
Enhancement of focusing properties of Bessel-like beam by metallic surface nanostructure

The focusing properties of a Bessel-like beam emitted from a circular slit surrounded by a surface groove (CSSG) were explored using experimental and numerical methods. The optical properties of the light emitted from the CSSG can be enhanced by using the scattered light from the surface groove. Furthermore, different modes of cylindrical surface plasmons in the circular slit are induced by different wavelengths of incident light, and beam shapes with a single spot and doughnut are created under illumination in the ultraviolet and visible regimes, respectively. A versatile beam shape is obtained from the CSSG structure.
