Bangladesh has one of the highest rates of malnutrition in the world although the country is endowed with agricultural produce that could be properly utilised to prepare adequate food for children. Considering this, three weaning foods were formulated using locally available cereals and nutritious fruits such as wheat, soya flour, jackfruit and mango. Methods: Standard procedures of Association of Official Analytical Chemists (AOAC) and American Public Health Association (APHA) were used to determine the chemical composition and microbiological analysis. Organoleptic qualities were analysed by twenty adult panelists of the Institute of Food Science and Technology, Bangladesh, using a 9-hedonic scale against a cereal based commercial brand as standard for proximate and sensory properties. Results: The moisture content of the developed weaning foods ranged from 2.78-3.59%, crude protein content 14.74-16.55%, fat 11.04-12.70%, ash 1.38-1.68%, crude fibre 1.04-1.52%, carbohydrate 65.83-71.09% and energy content from 445.80-465.48 kcal/100g of the foods. The formulated weaning foods A, B and C were significantly different (p<0.05) in moisture, protein, fat, carbohydrate and energy contents from the commercial brand, D. According to rat bioassay method, the prepared weaning foods C and B had the highest Protein Efficiency Ratio and Feed Efficiency Ratio than the commercial brand, D. Total bacterial counts were nil for all weaning foods. Sensory analysis revealed acceptability of all the weaning foods and preference for weaning food C that compared favorably with the standard in all the quality attributes. Conclusion: The formulated weaning foods are inexpensive and nutritious, and its ingredients are locally available. These foods have the potential for improving malnutrition problems facing children in Bangladesh.

Aims: Temporary Immersion Bioreactor (TIB) system is an advanced technology for commercial mass production of
potato microtubers. Despite of several advantages, this system possess a great risk of culture loss at any stage of
micropropagation due to microbial contamination. The aims of this study were to identify microbial contaminants isolated
during potato shoot growth in the TIB system, evaluate the efficacy of antimicrobial agents to prevent them, to
investigate the effect of those agents in vitro on growth and morphology of potato plantlets.
Methodology and results: Six bacteria namely Pseudomonas, Staphylococcus, Klebsiella, Corynebacterium, Proteus,
Bacillus and five fungi Aspergillus, Penicillium, Mucor, Fusarium and Rhizopus were isolated from the TIB system. We
examined the effect of three antibacterial (Gentamycin, Vancomycin and Tetracycline) and four antifungal agents
(Mencozeb, Propiconazole, Bavistin and Copper oxychloride) on the contaminants and on potato shoot growth. Results
show that Gentamycin (50 mg/L) and Propiconazole (0.15%) were most effective against the isolated bacteria (35 mm
inhibition zone) and fungi (100%) respectively, whereas Gentamycin in combination with Bavistin showed better
performance on potato shoot and root development.
Conclusion, significance and impact of study: Present study will provide useful guidelines to reduce or eliminate the
risk of contamination during micropropagation.

A newly synthesized Nickel (II) tyrosine complex was screened as potential antimicrobial agent against a number of medically important bacteria (Bacillus subtilis, Streptococcus beta-haemolytica, Escherichia coli, Shigella dysenterae) and fungi (Aspergillus fumigatus, Candida albicans, Aspergillus niger, Aspergillus flavus, Penicillium sp.) strains. were used for antifungal activity. The antimicrobial activity was evaluated using the Agar Disc method. Moreover, the minimum inhibitory concentration of the complexes was determined against the same pathogenic bacteria and the values were found between 4~64 microg ml(-1). Brine shrimp bioassay was carried out for cytotoxicity measurements of the complexes. The LC50 values were calculated after probit transformation of the resulting mortality data and found to be 6 microg ml(-1).

The nasal septum is a crucial supporting factor for the nasal cavity and may develop several anatomical variants including septal deviation, spur and pneumatization. These variants could be associated with a higher incidence of sinusitis due to structural and functional alterations. So, the aim of this study was to assess the prevalence of nasal septal deviation (NSD), nasal septal spur (NSS) and nasal septal pneumatization (NSP) among the Saudi adult population and their links with the incidence of sinusitis by using computed tomography (CT). A retrospective study was achieved over a twenty-two months period on 681 adult Saudi subjects (420 males and 261 females) aged 20 years or older, referred for coronal CT evaluation of the paranasal sinuses. NSD and NSS were significantly more prevalent in males than females (80.0% vs. 67.4% respectively for NSD, and 34.5% vs. 24.9% respectively for NSS), while there was no statistical difference in frequency of NSP regarding gender (P=0.670). The incidence of sinusitis was significantly higher in presence of NSD and/or NSS (P<0.001 for both). On the contrary, NSP was not associated with a significant increase in the prevalence of sinusitis (P=0.131). In conclusion, NSD and NSS are more prevalent in males than females among the Saudi population with no statistical difference between both genders regarding the presence of septal pneumatization. Furthermore, sinusitis is more prevalent with the occurrence of NSD and NSS, and not related to the incidence of NSP.

Goat ovaries were collected from the slaughterhouse and categorized as right, left, corpus luteum (CL)-present and -absent group and evaluated on the basis of weight (g), length (cm), width (cm), number of follicles, follicles aspirated and number and state ofcumulus-oocyte-complexes (COCs). Comparatively higher weight [(0.66±0.02) vs (0.64±0.02) g], length [(1.17±0.02)vs (1.11±0.02) cm] and width [(0.77±0.02) vs (0.74±0.02) cm] were found in right ovaries than those of left. On the other hand significantly (P<0.05) higher weight [(0.71±0.03) vs (0.64±0.01) g] and width [(0.76±0.03) vs (0.75±0.01) cm] were found in CL-present group than those of CL-absent group of ovaries. The left ovaries contained comparatively higher number of normal COCs [(1.06±0.09) per ovary] than right ovaries [(1.03±0.10) per ovary] and the similar trend was found in total number of follicles [(4.51±0.25) vs (4.30±0.23) per ovary] and follicles aspirated [(2.55±0.14) vs (2.52±0.12) per ovary]. But the total COCs per ovary was almost similar in both ovaries [right and left: (1.85±0.12) and (1.85±0.11) per ovary, respectively]. Higher number of total COCs [(1.87±0.09) vs (1.76±0.16) per ovary], total number of follicles [(4.45±0.19) vs (4.16±0.37) per ovary], follicles aspirated [(2.55±0.10) vs (2.48±0.21) per ovary] and normal COCs [(1.12±0.07) vs (0.76±0.14) per ovary] were found in CL-absent group than those of CL-present group of ovaries.

Effect of ethanolic extracts of Lawsonia inermis, Azadirachta indica, Vinca rosea, Tagetes patula, Ocimum sanctum, Colocasia antiquorum, Adhatoda vasica, Moringa oleifera, Datura metel and Curcuma longa leaf on conidial germination, mycelial growth and sporulation of Aspergillus flavus, A. niger and A. fumigatus were examined. The conidial germination of A. flavus and A. fumigatus were most inhibited by the extract of L. inermis, while that of A. niger was inhibited by A. indica. Other tested plant extracts have a good effect on conidial germination on the selected fungi. The highest mycelial growth of A. flavus (37 mm) was found in V. rosea, but in case of A. niger and A. fumigatus it (38 and 39 mm) was found in D. metel. The lowest (4, 9 and 6 mm) respectively mycelial growth of these fungi found in L. inermis. The highest sporulation (75 x 10(4)/ml) of A. flavus was counted in V. rosea, but in case of A. niger and A. fumigatus those (45 x 10(4) and 55 x 10(4)/ml) were in D. metel and the lowest (5 x 10(4), 12 x 10(4) and 9 x 10(4)/ml) respectively sporulation of these fungi counted in L. inermis plant extract medium.

PURPOSE: To compare the expression of survivin and its association with clinicopathological criteria in major types of urinary bladder carcinoma, specifically, transitional cell carcinoma with and without squamous differentiation and squamous cell carcinoma. MATERIALS AND METHODS: Immunohistochemical staining for survivin and Ki67 was performed on paraffin-embedded sections of 104 carcinomas: 52 transitional cell carcinoma, 20 transitional cell carcinoma with squamous differentiation, and 32 squamous cell carcinoma. Expression of survivin in >10% of tumor cells was described as altered survivin status. Ki67 staining in >20% of tumor cells was described as a high proliferation index. RESULTS: Altered survivin expression was detected in 60/104 specimens (58%) and was significantly more frequent in transitional cell carcinoma (78%) than in squamous cell carcinoma (38%) or transitional cell carcinoma with squamous differentiation (40%) (p<0.0001). In transitional cell carcinoma but not in squamous cell carcinoma, altered survivin status was associated with higher tumor grade, higher proliferation index, and recurrence. In the whole specimens, altered survivin expression was significantly associated with advanced stage (p<0.001), recurrence (p=0.005), distant metastasis (p<0.001), and death (p=0.001). In the multivariate analysis, altered survivin was an independent poor prognostic factor for recurrence. CONCLUSIONS: Unlike in transitional cell carcinoma, alteration of survivin expression in squamous cell carcinoma occurs less frequently and is not associated with features of tumor aggression or patient outcome. These findings raise a question: are urinary bladder carcinoma patients with squamous cell carcinoma type suitable candidates for survivin vaccine? This is an important question to be answered before approving the vaccine in management.

Vancomycin, an antibiotic used occasionally as a last line of treatment for methicillin-resistant Staphylococcus aureus, is reportedly associated with nephrotoxicity. This study aimed at evaluating the protective effects of lutein against vancomycin-induced acute renal injury. Peroxisome proliferator-activated receptor gamma (PPARγ) and its associated role in renoprotection by lutein was also examined. Male BALB/c mice were divided into six treatment groups: control with normal saline, lutein (200 mg/kg), vancomycin (250 mg/kg), vancomycin (500 mg/kg), vancomycin (250 mg/kg) with lutein, and vancomycin (500 mg/kg) with lutein groups; they were euthanized after 7 days of treatment. Thereafter, samples of blood, urine, and kidney tissue of the mice were analyzed, followed by the determination of levels of N-acetyl-β-D-glucosaminidase (NAG) in the urine, renal creatine kinase; protein carbonyl, malondialdehyde, and caspase-3 in the kidney; and the expression of PPARγ, nuclear factor erythroid 2-related factor 2 (Nrf2), and nuclear factor-kappaB (NF-κB) in renal tissue. Results showed that the levels of protein carbonyl and malondialdehyde, and the activity of NAG, creatine kinase and caspase-3, were significantly increased in the vancomycin-treatment groups. Moreover, the levels of Nrf2 significantly decreased, while NF-κB expression increased. Lutein ameliorated these effects, and significantly increased PPARγ expression. Furthermore, it attenuated vancomycin-induced histological alterations such as, tissue necrosis and hypertrophy. Therefore, we conclude that lutein protects against vancomycin-induced renal injury by potentially upregulating PPARγ/Nrf2 expression in the renal tissues, and consequently downregulating the pathways: inflammation by NF-κB and apoptosis by caspase-3.
