Corallus hortulanus testes histology: morphological and reproductive aspects.

In general snakes show differentiate anatomical, biological and behavioral particularities compared to other species. Basic information about the snakes anatomy, physiology and reproductive biology is scarce in several species, making the reproduction a challenge. Thus, the present work aims to evaluate morphological aspects of the Corallus hortulanus testes, correlating these findings with environmental factors and reproductive aspects.

Histological aspects of the renal sexual segment of Brazilian snakes of the Boidae family.

Snakes represent a wide and diverse group of species and have anatomical particularities, such as the renal sexual segment (RSS), a structure located in the kidneys and formed from the hypertrophy of the urinary ducts and nephrons. This study aims at describing the histological aspects of the RSS of Boa constrictor, Epicrates cenchria and Corallus hortulanus, all of which are Brazilian snake species from the Boidae family. The reproductive system and kidneys of five male specimens of E.

Ionic liquids and deep eutectic solvents for the stabilization of biopharmaceuticals: A review.

Biopharmaceuticals have allowed the control of previously untreatable diseases. However, their low solubility and stability still hinder their application, transport, and storage. Hence, researchers have applied different compounds to preserve and enhance the delivery of biopharmaceuticals, such as ionic liquids (ILs) and deep eutectic solvents (DESs).

Enzymatic production process of capric acid-rich structured lipids: Development of formulation as a new therapeutic approach.

The present work reports an optimization of the synthesis of MLM-type (medium, long, medium) structured lipids (SL) through an acidolysis reaction of grape seed oil with capric acid catalyzed by Rhizopus oryzae lipase immobilized. At first, tests were carried out by preparing the biocatalysts using enzyme loadings (0.15 to 1 g of enzymatic powder) for each gram of support.

Brazilian Boidae hemipenis morphology: Macroscopic and histological aspects.

Four genera of the Boidae family are found in Brazil: Eunectes, Corallus, Epicrates, and Boa. Male copulatory organs in snakes are located inside the tail and are called hemipenes. They are double structures in an inverted position that are exposed during copulation.

Aliivibrio fischeri L-Asparaginase production by engineered Bacillus subtilis: a potential new biopharmaceutical.

L-Asparaginase (L-ASNase) is an enzyme applied in the treatment of lymphoid malignancies. However, an innovative L-ASNase with high yield and lower side effects than the commercially available preparations are still a market requirement. Here, a new-engineered Bacillus subtilis strain was evaluated for Aliivibrio fischeri L-ASNase II production, being the bioprocess development and the enzyme characterization studied.

Xylanase Production by Valuing Agroindustrial Byproducts.

In general, agroindustrial byproducts can be easily assimilated by several microorganisms due to their composition, which is rich in carbohydrates. Therefore, they could be appropriate for use as raw materials in a sustainable refinery concept, including the production of hydrolytic enzymes with industrial applicability. In this work, xylanase production by the filamentous fungi in submerged culture was evaluated using five agroindustrial byproducts, namely, wheat bran, citrus pulp, rice bran, peanut skin, and peanut shell.

Use of Fungal Mycelium as Biosupport in the Formation of Lichen-like Structure: Recovery of Algal Grown in Sugarcane Molasses for Lipid Accumulation and Balanced Fatty Acid Profile.

In this study, a lichen-like structure was obtained through the production of a unique biomass, formed by algae cells of adhering to the mycelium of filamentous fungal This structure was composed in two steps; in the first one, microalgal cells and spores were incubated separately, and in the second one, after 72 h of growth, isolated, mature mycelium was harvested and added to cell culture. For spores' incubation, a culture medium containing only 2 g·L of glucose and minerals was used. This culture medium, with low sugar content, provided a fungal biomass to the anchorage of microalgae cells.

L-asparaginase production review: bioprocess design and biochemical characteristics.

In the past decades, the production of biopharmaceuticals has gained high interest due to its great sensitivity, specificity, and lower risk of negative effects to patients. Biopharmaceuticals are mostly therapeutic recombinant proteins produced through biotechnological processes. In this context, L-asparaginase (L-asparagine amidohydrolase, L-ASNase (E.

Urethral catheterization after pharmacological induction for semen collection in dog.

The α-adrenergic agents are known to influence erection and ejaculation, and ejaculatory reflex is a primarily α-adrenergically mediated event. This paper aims to describe the urethral catheterization technique after pharmacological induction for semen collection in domestic dogs. For dose determination, semen collection was performed using increasing doses of dexmedetomidine (5 μg/kg, n = 2; 10 μg/kg, n = 2 and 15 μg/kg, n = 2) associated to 3 mg/kg ketamine in six animals.

Pasteurella canis infection in a non-human primate black-tailed marmoset (Mico melanurus)-A case report.

This study reports the pathological and microbiological findings of pneumonia in a Mico melanurus caused by Pasteurella canis, confirmed for molecular analyses. It demonstrated the importance that wild species represent in the epidemiology of pasteurellosis in anthropic environments, when inserted into urban areas.

Critical applications of Mucor circinelloides within a biorefinery context.

The establishment of an efficient and feasible biorefinery model depends on, among other factors, particularly the selection of the most appropriate microorganism. Mucor circinelloides is a dimorphic fungus species able to produce a wide variety of hydrolytic enzymes, lipids prone to biodiesel production, carotenoids, ethanol, and biomass with significant nutritional value. M.

Sustainable enzymatic approaches in a fungal lipid biorefinery based in sugarcane bagasse hydrolysate as carbon source.

Single cell oil (SCO) was produced from enzymatically hydrolysed sugarcane bagasse by Mucor circinelloides. The fungus was cultured in the hydrolysate medium rich in glucose and xylose being able to assimilate both sugars simultaneously, attaining satisfactory values of lipid accumulation (25 wt%). The main concepts addressed herein were the utilization of these lipids for the production of (i) ethyl esters of fuel grade, and (ii) concentrate of polyunsaturated fatty acids for nutraceutical applications.
