Xylanase constitutes 20% of world enzyme market. Significantly, they are used in poultry feed, paper pulp, bakery, and textile industries. In view of the increasing demand of the enzyme, it is vital to develop indigenous strains and scalable technologies for the production of industrial enzymes.

The objective of the present paper was to isolate a high-yielding strain of thermo-alkali-stable xylanase-producing bacteria for potential application in paper and pulp and biofuel industry.

Sampling for prospecting of suitable organism was carried out from the places with dead and decaying lignocellulosic waste, and then Congo red screening was employed for the primary isolation of xylanase producers.

We report the isolation of 18 different strains of xylanase producer bacteria from natural hot water geyser of Sohna, Haryana, India. Subsequently, two of these isolates were chosen for further studies based on xylanase yield and desirable properties such as thermostability and alkali stability of xylanase produced.

Isolate B2 was later identified as
, whereas isolate Y3 was identified as
. This strain when cultured at 35°C for 72 h showed xylanase production at 128 U/ml. The molecular weight of xylanase was determined to be 25 kDa. The production was scaled up in a 5-L stirred-tank bioreactor which led to high xylanase concentration of 380 U/ml in the first 48 h of culture.
Isolate B2 was later identified as Bacillus licheniformis, whereas isolate Y3 was identified as Brevibacillus borstelensis.

The production was scaled up in a 5-L stirred-tank bioreactor which led to high xylanase concentration of 380 U/ml in the first 48 h of culture.
The olfactory system is one of the most important chemosensory systems for teleosts. The olfactory epithelium of freshwater catfish
(
,
) was studied by the aid of light microscopy and transmission electron microscopy.

Mature sex-independent fish species were collected from Hooghly River, a distributary channel of river Ganga. Following routine procedure of ultrastructural techniques, different sensory and nonsensory cells lining the olfactory epithelium were described.

The lamella contained two epithelia, with a central core sandwiched in between. Based on distribution pattern and structural characteristics of cell, each olfactory lamella was differentiated into sensory and nonsensory epithelium. The smaller sensory epithelium contained morphologically distinct ciliated, microvillous, and rod receptor cells, distinguished based on staining patterns, characteristic length, and architecture of their dendritic terminals. The nonsensory epithelium comprising the greater surface area was made up of labyrinth cells, mast cells, supporting cells, ciliated nonsensory cells, and basal cells. The cilia furnished a characteristic 9 + 2 microtubule arrangement.

The functional significance of various cells on the olfactory epithelium was correlated with behavior of the fish concerned.

Breast lesions extend from benign to malignant ones. The National Cancer Institute recommended categories for the diagnosis of breast cytology. There are some lesions in the breast which are called intermediate or gray lesions. It includes C3 (atypical, probably benign) and C4 (suspicious, favor malignant) which needs to be evaluated.

This study was conducted in the Department of Pathology, Uttar Pradesh University of Medical Sciences, Saifai, Etawah (Uttar Pradesh). Fine-needle aspiration cytopathology (FNAC) was the diagnostic tool. The present study was undertaken to determine the gray lesions of the breast and its correlation with histopathology and other associated parameters. Immunohistochemistry was applied where ever necessary. One hundred and fifty one cases of gray lesions of the breast were included.

C3 was seen in 85 (56.29%) and C4 in 66 (43.70%) patients. The maximum number of patients was of 31-40, (33.77%) years age group, the youngest patient was 12-year-old female, whereas the oldest wsions need to be evaluated because of the risk of malignancy. However, gray lesions can be reduced by cytology followed by histopathology examination along with ancillary radiological investigations such as mammography and ultrasonography.
Fineneedle aspiration cytology of the breast is well accepted and accurate for the diagnosis of benign and malignant lesions, however, it remains a subjective evaluation.

The present study was carried out to assess the utility of nuclear morphometry in differentiating benign and malignant breast aspirates. Importantly, we wanted to evaluate the utility of nuclear density parameters using Image J software.

Nuclear morphometry was carried out using image analysis software Image J 1.44 on 20 selected benign and malignant breast aspirates. Assessment was carried out on a total of 1000 cells in benign and 1000 cells in malignant aspirates counting 50 intact nuclei in nonoverlapping cells for each case. Six parameters including three size parameters, namely nuclear area, nuclear diameter, and nuclear perimeter; one shape parameter, i.e., axis ratio; and two nuclear chromasia parameters, namely density (integrated and raw), were measured.

There were significant differences between nuclear area, perimeter, diameter, integrated density, and raw integrated density of benign and malignant lesions. No significant difference was found for axis ratio. Receiver operating characteristic curve analysis revealed that nuclear area, perimeter, diameter, integrated density, and raw integrated density are helpful in discriminating benign and malignant aspirates.

Thus, Image J is helpful in the evaluation of nuclear size as well as chromasia. We conclude that nuclear size and density parameters can be used to derive cutoff values of various parameters to differentiate between benign and malignant cells in breast cytology.

Umbilical cord plays a crucial role in the continuation of pregnancy by transferring nutrition and oxygen across the placenta to the fetus. Selleck BMS493 We aimed to investigate the morphometrical and histological features of the umbilical cords in new-born rats.

The adult male and female rats were chosen for matting purpose in the present study. Briefly, ten adult
rats (female,
= 5; male,
= 5) were randomly assigned into five groups of two animals (female,
= 1; male,
= 1). Immediately after parturition, two umbilical cords of new-born rats (0-day-old) from each group were randomly selected. Finally, ten umbilical cord samples were examined using the histological and stereological methods in the light and electron microscopes.

The total numbers of Hofbauer cells and mesenchymal stromal cells was estimated statistically. We also calculated the mean volume of umbilical cords, arteries and veins, as well as arterial and venous lumens. Our histological findings also exhibited the histological features of Hofbauer cells, mesenchymal stromal cell cells, and blood vessels.

Our findings showed more detailed information about umbilical cord tissues and their components, and that may contribute to the diagnose of umbilical cord complications in the developing fetus.

The aim was to assess the risk of osteopenia and osteoporosis and to identify possible risk factors affecting bone density (BD) during pregnancy as parity, body mass index (BMI), Vitamin D, and calcium supplementation using quantitative ultrasound (QUS) of the calcaneus among first- and third-trimester pregnant women.

It is a case-control study conducted at Ain Shams Maternity Hospital, Egypt, from May 7 to December 14, 2015. One hundred and thirty-two women in the third trimester and 33 matched controls in the first trimester were screened for BD at the calcaneus by QUS. Stiffness index (SI), QUS-T, and Z scores were measured.

Comparing both the groups regarding QUS-T score, Z score, and SI showed a statistically significant difference between both groups. Third-trimester participants had lower scores (-0.72 ± 1.0, -0.63 ± 0.99, and 88.53 ± 14.81, respectively) compared to their matched controls (1.05 ± 0.89, 1.16 ± 0.91, and 113.79 ± 12.49, respectively). According to QUS-T scores, 82 women (62.1%) in the third-trimester group were assessed as having normal BD, whereas 47 women (35.6%) were at risk of being osteopenic and 3 women (2.3%) were at risk of being osteoporotic. All women of the first trimester were assessed as having normal BD. Logistic regression was performed to identify possible risk factors affecting BD among third-trimester patients. BMI was the only statistically significant predictor for changes in bone health in those women (
= 0.001, odds ratio 0.857, 95% confidence interval 0.786-0.936).

With one-unit rise in BMI, a 14% reduction in risk of decreased bone health is obtained.

The patient was initially diagnosed with Henoch-Schönlein purpura and presented with worsening symptoms with significant necrosis of her perineum and rectum requiring surgical debridement and diverting colostomy. As a part of her work-up, she tested positive for COVID-19 total IgG/IgM antibodies and ANCA antibodies. This case complements previously reported cases of COVID-19 induced autoimmune disease in children but is novel in describing extensive intestinal disease as a result of an autoimmune vasculitis in a child.E-learning programmes have become established in postgraduate oral medical education and training. Internet and literature researches show a variety of good concepts that provide an attractive alternative to face-to-face training. What is missing is an overall concept in which continuing education and training are offered in bundled form in various teaching and learning formats. We discuss the blended learning concept which offers the best options, which has been proven by scientific studies. Using the example of the International Medical College (IMC) at the University of Duisburg-Essen, a blended learning overall concept for postgraduate continuing education is presented.
