Wood is a material used in construction, in instrument making, etc. In Benin, for heavy construction and construction on wetland, species with high technological characteristics are imported. But the performance of these imported species compared to local indigenous or exotic species remains to be verified. Thus, it is necessary to determine the basic technological properties of these species. It is within this framework that we have, on 500mmÃ—20mmÃ—20mm prismatic wood specimens of Anogeissus leiocarpus, Manilkara multinervis and Cylicodiscus gabunensis, used the acoustic method BING (Beam Identification by Non-destructive Grading) of CIRAD-Forest to determine the density Ï, the moduli of Young's modulus E, shear modulus G and the internal friction tanð›¿ and then evaluated the modulus of specific stiffness E/Ï. On other 20 mm edge cubic specimens, we evaluated the reference physical properties of density, infradensity, total shrinkage, radial shrinkage, tangential shrinkage and shrinkage anisotropy. It appears that the wood of Anogeissus leiocarpus and Manilkara multinervis present better physico-mechanical characteristics than those of Cylicodiscus gabunensis. Anogeissus leiocarpus and Manilkara multinervis are very dense woods with physico-mechanical characteristics better than those of most Benin's popular species. The average modulus of elasticity in bending of these two species is higher than 12000 MPa while that of Cylicodiscus gabunensis is 10713 MPa. In compression all these species have an average modulus of elasticity above 14100 MPa.Â Cylicodiscus gabunensis wood tested is light with a lower shrinkage anisotropy than the other two species studied and have excellent acoustic properties. Its average specific stiffness (14 GPa) is higher than that of the other two species studied (12 GPa). The good physical-mechanical and acoustic properties of these species show that they are good structural timbers with also good potential for instrument making and acoustic insulation.Keywords: BING; Construction; Infradensity; Modulus of elasticity; Shrinkage anisotropy; Timber.

The almost irreversible and encouraged link between connectable computer terminals and playful juvenile occupation raises the issue of parental education in the family environment. The latter is characterized by its narrowness and the almost daily absence of parents, hence the question of the uncontrolled use of tablets and smartphones connected by Middle School students from Pikine. Thanks to qualitative methods and semi-structured interviews with fourteen (14) teenagers and their parents, we discover that fathers and mothers are missing from homes on a daily basis because of work. They give to their offspring these devices and the connection not only to occupy them usefully but also to protect them from the evil temptations of the outside. Free, these young people, devote themselves to video games, sports, music, pornography, etc. offered by different websites. Thus, they idealize and copy bad models taken from the net. Conflicts with parents arise. Sanctions follow and the most painful is the withdrawal of the devices.Â Â

Simplex machine plays a vital role in spinning process. By using simplex machine the roving has been found, which reduced maximum draft in the ring frame. So it is necessary to produce good qualities roving from simplex machine. For this reason the draft and amount of false twist has been kept at a particular ration. For controlling draft, the drafting arrangement needed to arrange in a proper order. The gauge distance between the drafting zones are needed to maintain at a particular distance, through which the production and the quality of the product will be optimum level. Here for the research work the simplex machine drafting arrangement is 4 over 4 and diameter of the rollers are 28.5 mm. For this reason three drafting zones have been formed, they are front, middle and back zone. Here the roving hank has been used is 0.80 and this roving is used for producing 26 Ne and 32 Ne cotton carded yarn. By using the same roving hand and changing the gauge distances, itâ€™s easily identified which gauge distance is suitable for producing roving as well as the quality of ring yarn.Â Â

Introduction: Immunization strengthens the defense mechanism of the body and offers protection against potential diseases. The rate of immunization is one of the best measures of public health management and quality. To increase the rate of immunization, parental decisions about vaccinations are very necessary. Parents' knowledge and attitude towards immunization influence the prevalence of infectious diseases. Moreover, vaccination is considered one of the most cost-effective public health tools to prevent infectious diseases.Objective: The objective of this study is to assess the frequency of adequate knowledge, positive attitude and good practices of mothers regarding immunization.Materials and Methods: It was a cross-sectional study which was conducted in The Children's Hospital & Child Health Institute, Lahore. A total of 125 children who met the selection criteria were enrolled. Parents were then questioned and validated by vaccination card status regarding various Expanded Immunization Policy (EPI) vaccinations and complete previous records. The awareness and attitude of mothers regarding vaccination was also considered that either they were aware of the vaccination status or not. All the data was collected and reported in the form of a questionnaire.Results: In this study93 mothers had a good understanding, 77 mothers had a good practice, and 66 mothers had a positive attitude towards immunization. Childsâ€™ gender, mothersâ€™ educational status, socio-economic status, good practice, and positive attitude had no significant impact on adequate knowledge about vaccination.Conclusion: It was concluded from this study that mothersâ€™ knowledge about immunization was adequate, however good practice and positive attitude were not up to the mark.Â Â

Published: March 2023

Thyrotoxic periodic paralysis is a unique disorder that causes episodic proximal lower extremity muscle weakness in a patient who already has a hyperthyroid state and is not treated for the underlying disease state. The affected population mostly includes Asian in origin specifically the male gender (vs most thyroid disorder affects the women gender). Precipitating factors include in addition to a hyperthyroid state are strenuous exertion, a high-carbohydrate meal, and drugs like diuretics, insulin, high dose of steroids, antiretrovirals, and interferon therapy. Other genetic causes include the decreased activity of Kir2.6 mutation increased activity of Na+/K+ ATPase causing an intracellular shift of potassium that leads to hypokalaemia. The other challenging part for the physician is to differentiate it from Familial periodic paralysis an autosomal disorder seen in Caucasians and Western countries because both the disorders present similarly and differentiate between them by the presence of hyperthyroid state with hypokalaemia in Thyrotoxic periodic paralysis. The mortality is associated with respiratory paralysis hence the acute intervention includes giving nonselective beta-blockers followed by anti-thyroid medications. We present a case of an Indian adolescent who presented to us with lower muscle weakness with an underlying thyrotoxicosis state. This help physician with early diagnosis and appropriate treatment.Â Â Â

Published: March 2023

Homocystinuria follows an autosomal recessive pattern and transpires due to Cystathionine beta-synthase enzyme deficiency. This condition is associated with thrombotic and thromboembolic complications due to an increase in homocysteine and methionine levels in the plasma and urine. We present a case of an Indian adolescent boy who presented to us with generalized tonic clinic seizure and Broca's aphasia he was diagnosed as having homocystinuria type 1, and he responded well to treatment.Background: Stroke and seizure disorders in young adults have increased substantially and are a relatively common disorder that presents in the emergency department in all age groups. Secondary seizures are more common and manifest as a result of another underlying pathology. This case demonstrates the importance of considering rarer causes of thrombosis such as arterial thrombosis, even in younger patients, with no obvious risk factors or comorbidities. A detailed medical history and thorough investigations need to be taken to identify a potentially treatable underlying cause.Objective: To increase awareness about this rare etiology and help clinicians to have a higher level of suspicion to diagnose this condition and prevent future life-threatening complications in younger patients with thrombotic and thromboembolic events.Â Â Â

Hyperlipidemia is an umbrella term that refers to any disorder of elevated level of lipids circulating in the blood; and is considered the most significant risk factor contributing to the prevalence of cardiovascular, hepatic, and other diseases. The present study was designed to evaluate the possible antihyperlipidemic potential Punica granatum mesocarp extract (PGME) in albino rats using high-fat diet model of hyperlipidemia. Forty-two albino rats were utilized in this experiment arranged randomly in seven groups, six rats each, of different treatments. Hyperlipidemia model was induced by incorporating coconut oil (1.5% w/w) and cholesterol (1.5 % w/w) in diet supplied to rats, for 6 weeks (+ve control); test group rats received PGME at escalating doses of 100 or 200 mg/kg, orally, daily for 6 weeks with keeping on high-fat diet; standard group rats received Rosuvastatin at dose of 2 mg/kg, orally, daily for 6 weeks along with high-fat diet; further 2 groups of rats received only PGME at the same dose levels with keeping on normal diet; while rats of -ve control group received only the vehicles of the used agents. Blood samples were picked out at the end of the experimental course for different assays. Clinicochemical analyses revealed that PGME exhibited dose-dependent protection against hyperlipidemia indicated by improved biomarkers, including, lipid profile parameters, namely cholesterol, triacylglycerols and lipoproteins; enzymatic hepatic parameters, namely, AST, ALT, and GGT; and non-enzymatic parameters, namely, total protein, albumin, globulins, total bilirubin, conjugated bilirubin, unconjugated bilirubin. The mechanism of the obtained lipid profile improvement of PGME may be based on the phytochemical principals Tannins, Phenolics and Flavonoids, indicated by preliminary detection tests. Data of the present study may suggest PGME as a good natural source for promising antihyperlipidemic remedies.Â Â

Complex probiotic preparations with spore-forming microorganisms of the genus Bacillus and other types of bacteria in their composition have a high biological activity and are of scientific and practical interest. In our laboratory experiments, we determined the level of antagonistic activity of the newly developed probiotic preparation containing strains of bacteria B. subtilis, B. licheniformis, B. coagulans in a complex with Enterococcus faecium, products of their own fermentation, other natural substances and a sorbent made of natural aluminosilicates. The antagonistic properties of the probiotic preparation were examined by diffusion methods of delayed antagonism and agar blocks. In order to identify the antagonistic action of the experimental probiotic preparation, we used Gram-negative and Gram-positive test cultures of bacteria from the Museum of Strains of Microorganism Cultures of the Research Bacteriology Department. The results of laboratory studies indicated the antagonistic effectiveness of the experimental probiotic preparation in its interaction with test microorganisms. This was confirmed by the indicators of the diameters of the growth inhibition zones of the tested bacteria, ranging 27–36 and more and corresponding to high and very high levels of antagonistic activity of the experimental probiotic. The use of the developed probiotic preparation in poultry farming would ensure the correct formation of microbiocenosis in gthe astrointestinal tract of poultry from hatching, increase local immunity, support a stable epizootic situation by preventing bacterial infections among poultry through biological means, and therefore contribute to production of ecologically high-quality and safe products of poultry farming.
Patho-histological features of fibroblastic sarcoid in horses
Authors: Portenko M. , Shchebentovska O. 
Published: March 2023

Sarcoid is one of the most common skin tumours, which is diagnosed in various breeds of horses at any age regardless of the animal’s sex. Such fibroblastic neoplasm manifests itself in several clinical ways with its specific morphological features. As a rule, it metastasizes rarely but can be locally invasive. The disease’setiology is multifactorial and includes the confirmed role of the bovine papillomavirus and genetic and environmental factors. The article introduces the results of a retrospective study of horses of the Ukrainian riding breed with a fibroblastic sarcoid type, which was localized mainly in the area of the external thoracic vein. Neoplasms were represented by two types. The first one included broad base neoplasms without a pronounced pedicle but with signs of hyperkeratosis. Massive rounded dense formations with an ulcerated surface refer to the second type. To verify the studied types of sarcoid, wide surgical excision of the lesion’svisible parts was performed, followed by the selection of fragments for the pathohistological diagnosis. Also, additional staining methods were used to detect the connective and muscle tissue (Van Gieson’s staining) and elastic fibers (Weigert’s resorcin-fuchsin staining). Microscopically, the neoplasm without a visible pedicle showed signs of hyperkeratosis and acanthosis in the peritumoral epidermal layer. Epidermis desquamation with a significant amount of oxyphilic detritus, diapedesis hemorrhages, and dilated vessels was also detected in some areas. Chaotic placement of fibroblasts and fibrocytes was noted, to a greater extent, subdermally. Anisocytosis and anisokaryosis were expressed moderately. Sarcoids, macroscopically presented in the form of massive dense formations with an ulcerated surface, were histologically characterized by the replacement of the epidermis with cellular elements, subdermal hemorrhages, and the characteristic perpendicular orientation of coarse collagen fibers towards the basement membrane. Closely spaced spindle-shaped cells with fibers forming moiré structures were visualized in the deep dermis layers. Nuclei were hyperchromic and elongated in shape, no atypical mitoses were noted. Pathohistological examination during the identification of a sarcoid type for diagnostic purposes can cause rapid growth and formation of an ulcer. The final diagnosis regarding equine sarcoid can be made based on a combination of clinical signs, histopathological examination, and molecular genetic testing with the isolation of BPV DNA.

Taking into account the progress of understanding diagnosis, course prognosis, evaluation of effectiveness of therapy of inflammatory bowel disease and also differentiation diagnosis between its main forms – ulcerative colitis and Crohn’s disease, the search for efficient non-invasive markers for solving those issues is extremely relevant. The patients were divided into groups depending on nosology and severity of the course of the disease. All the patients had undergone endoscopic study for diagnosis verification and biopsy samples were taken for further detection of tissue IgG4 using the immunohistochemical method. Also, we determined concentration of serum IgG4. Increase in IgG4content in blood serum was determined in 54.0% of the cases of inflammatory bowel disease. Concentration of IgG4 in patients suffering ulcerative colitis was higher (by 2.31 and 2.46 times) compared with its level in the control group and patients with Crohn’s disease, respectively. We found relationships between the concentration of serum IgG4 and the activity of the disease. In patients with ulcerative colitis, increased tissue IgG4 was found more often than in patients with Crohn’s disease (by 2.77 times, Р < 0.05). We determined the relationship between tissue IgG4 and histological activity. Simultaneous increase in serum IgG4 and presence of tissue IgG4 during ulcerative colitis were more frequent than during Crohn’s disease (by 2.66 times). In all examined groups of patients, we determined decrease in serum IgG4 content (by 1.66 times) after treatment. Concentration of serum IgG4 and positive tissue IgG4 in ulcerative colitis patients exceeded such in Crohn’s disease patients, which may be used for differentiation diagnosis between those disease types. We determined dependence of IgG4 concentration on severity and duration of the disease, which could be used as a prognostic marker. Decrease in IgG4 content in blood serum against the background of the therapy shows that this indicator could be used as a marker of treatment efficacy. Perspectives of further studies are as follows: parameters of concentration of serum IgG4 and presence of tissue IgG4 could be used as diagnostic and prognostic biomarkers and be introduced to practice for differentiation diagnosis between ulcerative colitis and Crohn’s disease, and could be used as prognostic marker of severity of the disease and therapy efficacy.

Imidacloprid is one of the most widely used insecticides in the world. The neurotoxicity of imidacloprid in adult amphibians has not been studied thoroughly. We investigated the expression of glial fibrillary acidic protein (GFAP), neurofilament light chain (NfL) and angiostatin in the amphibian brain to identify valid biomarkers of low dose imidacloprid exposure. For the experiment, 30 individuals of the marsh frog Pelophylax ridibundus were selected. The amphibians were divided into five groups. The duration of the experiment was 7 and 21 days. The exposure concentrations were 10 and 100 µg/L. The results of the study revealed a decrease in the expression of GFAP after 7 days in the exposure groups of 10 and 100 μg/L. An increase in the level of NfL was observed in the group exposed to 10 μg/L after 21 days of the experiment. The angiostatin level was increased after 7 days at 10 µg/L and after 21 days at 100 µg/L. The data obtained indicate that low concentrations of imidacloprid can cause neurotoxic effects in the brain of P. ridibundus. Such effects can have a significant impact on amphibian populations. According to the results of the study of the expression level of GFAP, NfL and angiostatin, it can be stated that imidacloprid has a neurotoxic effect on adult marsh frogs. The studied indicators can be promising biomarkers of environmental pollution by neonicotinoids.
