Purpose: Nocturia significantly impacts patients’ quality of life but remains insufficiently evaluated and treated. The “Sleep C.A.L.M.” system categorizes the factors thought to collectively reflect most underlying causes of nocturia (Sleep disorders, Comorbidities, Actions [i.e., modifiable patient behaviors such as excess fluid intake], Lower urinary tract dysfunction, and Medications). The purpose of this study was to assess the association of nocturia with the Sleep C.A.L.M. categories using a nationally representative dataset. Methods: Retrospective analysis of the National Health and Nutrition Examination Survey from 2013/14–2017/18 cycles was conducted. Pertinent questionnaire, laboratory, dietary, and physical examination data were used to ascertain the presence of Sleep C.A.L.M. categories in adults ≥20 years of age. Nocturia was defined as ≥2 nighttime voids. Results: A total of 12,274 included subjects were included (51.6% female; median age, 49.0 years [interquartile range, 34.0–62.0 years]; 27.6% nocturia). Among subjects with nocturia, the prevalence of 0, ≥1, and ≥2 Sleep C.A.L.M. categories was 3.5% (95% confidence interval [CI], 2.8%–4.4%), 96.5% (95% CI, 95.6%–97.2%), and 81.2% (95% CI, 78.9%–83.3%), respectively. Compared to those with 0–1 Sleep C.A.L.M. categories, the adjusted odds of nocturia in subjects with 2, 3, and 4–5 Sleep C. A.L.M. categories were 1.77 (95% CI, 1.43–2.21), 2.33 (1.89–2.87), and 3.49 (2.81–4.35), respectively (P<0.001). Similar trends were observed for most age and sex subgroups. When assessed individually, each of the 5 Sleep C.A.L.M. categories were independently associated with greater odds of nocturia, which likewise persisted across multiple age and sex subgroups. Conclusions: Sleep C.A.L.M. burden is associated with increased odds of nocturia in a dose-dependent fashion, and potentially a relevant means by which to organize the underlying etiologies for nocturia among community-dwelling adults.

Conception Rate of Pabna Cows and Heifers Bred Under Artificial Insemination and Natural Service

Howlader, M.M.R.,Mian, M.F.,Kamal, A.H.M.,Prodhan, M.A.M.,Rahman, M.F. Asian Australasian Association of Animal Productio 1997 Animal Bioscience Vol.10 No.3

A study on the conception rate of 885 cows and heifers bred under artificial insemination (AI) and natural service was carried out at AI sub-centers. A high conception rate was observed at first service in all breeding methods. It was revealed that the conception rates in AI with liquid semen (LS) were found to be 25.08, 18.58, 12.69, and 2.48% after 1, 2, 3 and 4 services, respectively. Inseminations of cattle with frozen semen (FS) were found to achieve 42.15, 14.46, 5.85, and 2.46% conception rates after 1, 2, 3, and 4 services, respectively. In natural service, conception rates were found to be 62.45, 6.75, 5.91, and 4.64%, respectively, after 1, 2, 3, and 4 services. Insemination of cows and heifers at mid-cycle had significantly (p < 0.05) higher conception rate as compared to early and late cycles. The existing AI machineries and breeding management need to be improved to achieve higher conception rate of dairy cattle under AI.

Monoclinic bismuth vanadate (m-BiVO4 ) has attracted many researchers as an advanced photocatalyst for hydrogen production via water splitting and degradation of organic contaminants. In this study, pure m-BiVO4 nanoparticles were fabricated by an easy reproducible solid state route at different temperatures (500 °C, 550 °C, 600 °C, 650 °C and 700 °C) for 2 h. The synthesized materials were characterized by X-ray Diff ractometer where all the diff raction patterns reveal characteristic peaks corresponding to m-BiVO 4 with space group C2/c. Obtained m-BiVO4 particles have the lattice parameters: a = 7.2477 Å, b = 11.6970 Å, c = 5.0900 Å and the volume of the unit cell is 309.23 (106 pm 3 ). Fourier Transform Infrared spectroscopy exhibits formation of Bi–O bond in the prepared nano powders. Ultraviolet–Visible diff use refl ectance spectroscopy suggests that nanostructured BiVO4 particles possess strong energy absorption properties both in visible and ultraviolet region. The particles show red shift of band gap as the calcination temperature rises and possible reasons have been discussed. Energydispersive X-ray spectroscopy confi rms presence of Bi, V, and O without any contaminant, while particle’s morphology was investigated using Field Emission Scanning Electron Microscope.

A year round study was carried out to investigate the etiology, clinical signs, postmortem lesions and occurrence of naturally occurring enterotoxaemia in Black Bengal goats. Sixteen goats of different age and sex died in different seasons with sigh associated with entero-toxaemia made the materials of this study. Accidental access to large amount of concentrate was noted as one of the predisposing factors although few cases were reported to occur without known diet change. Younger animals(50%) and males(62.50%) were found more prone to the disease and it was likely to be more prevalent during winter(50%) followed by at rainy season(31.25%) and summer(18.75%). Diarrhoea(81.25%), dullness(56.25%), drooping of the ears(50%), anorexia(43.75%) were recorded as major clinical signs whereas enterocolitis(100%), lung edema(87.50%), fluid filled intestines(87.50%), enlarged mesenteric lymph nodes(56.52%) etc. were most common post mortem lesions found. A few cases showed lesions on heart(31.25%), brain(25%) and/or liver/spleen(18.75%) but no lesion was found on kidney. Thus the so called ``pulpy kidney`` lesion was absent. Intestinal contents were subjected to conventional bacteriological culture based methods to identify the causal agents. Based on the morphological, cultural and biochemical properties the causal agent was identified as Clostridium perfringens. Despite the study was carried out at certain area it showed a clear picture of goat enterotoxaemia in terms of etiology, clinical signs, postmortem lesions and occurrence of goat enterotoxaemia in Bangladesh.

STRAINS OF FOOT-AND-MOUTH DISEASE VIRUS IN DIFFERENT DISTRICTS OF BANGLADESH

Chowdhury, S.M.Z.H.,Rahman, M.F.,Rahman, M.B.,Rahman, M.M. Asian Australasian Association of Animal Productio 1996 Animal Bioscience Vol.9 No.3

An investigation was carried out to find out the strains of foot-and-mouth disease (FMD) virus in 24 districts of Bangladesh. A total of 505 FMD virus samples were collected from June, 1989 to June, 1991 and tested by complement fixation test (CFT). Of these, 276 (54.7%) were found positive for different strains of FMD virus and the rest 45.3% were either negative or anticomplementary. Strains identified were O, C, Asia-1 and sub-strains $A_5$ and $A_{22}$. Strain O was found to be most prevalent(39.8%) followed by Asia-1 (5.7%), C (5.3%), $A_5$ (3.4%) and $A_{22}$ (0.4%). Prevalence of sub-strain $A_5$ was reported for the first time in Bangladesh. District-wise typing of FMD virus has been done which would be helpful for appropriate vaccination programme in different districts of Bangladesh for control of the malady.

Effects of the incorporation of ε-aminocaproic acid/chitosan particles to fibrin on cementoblast differentiation and cementum regeneration

Park, C.H.,Oh, J.H.,Jung, H.M.,Choi, Y.,Rahman, S.U.,Kim, S.,Kim, T.I.,Shin, H.I.,Lee, Y.S.,Yu, F.H.,Baek, J.H.,Ryoo, H.M.,Woo, K.M. Elsevier Science B.V. Amsterdam 2017 ACTA BIOMATERIALIA Vol. No.

Cementum formation on the exposed tooth-root surface is a critical process in periodontal regeneration. Although various therapeutic approaches have been developed, regeneration of integrated and functional periodontal complexes is still wanting. Here, we found that the OCCM30 cementoblasts cultured on fibrin matrix express substantial levels of matrix proteinases, leading to the degradation of fibrin and the apoptosis of OCCM30 cells, which was reversed upon treatment with a proteinase inhibitor, ε-aminocaproic acid (ACA). Based on these findings, ACA-releasing chitosan particles (ACP) were fabricated and ACP-incorporated fibrin (fibrin-ACP) promoted the differentiation of cementoblasts in vitro, as confirmed by bio-mineralization and expressions of molecules associated with mineralization. In a periodontal defect model of beagle dogs, fibrin-ACP resulted in substantial cementum formation on the exposed root dentin in vivo, compared to fibrin-only and enamel matrix derivative (EMD) which is used clinically for periodontal regeneration. Remarkably, the fibrin-ACP developed structural integrations of the cementum-periodontal ligament-bone complex by the Sharpey's fiber insertion. In addition, fibrin-ACP promoted alveolar bone regeneration through increased bone volume of tooth roof-of-furcation defects and root coverage. Therefore, fibrin-ACP can promote cementogenesis and osteogenesis by controlling biodegradability of fibrin, implicating the feasibility of its therapeutic use to improve periodontal regeneration. Statement of Significance: Cementum, the mineralized layer on root dentin surfaces, functions to anchor fibrous connective tissues on tooth-root surfaces with the collagenous Sharpey's fibers integration, of which are essential for periodontal functioning restoration in the complex. Through the cementum-responsible fiber insertions on tooth-root surfaces, PDLs transmit various mechanical responses to periodontal complexes against masticatory/occlusal stimulations to support teeth. In this study, periodontal tissue regeneration was enhanced by use of modified fibrin biomaterial which significantly promoted cementogenesis within the periodontal complex with structural integration by collagenous Sharpey's fiber insertions in vivo by controlling fibrin degradation and consequent cementoblast apoptosis. Furthermore, the modified fibrin could improve repair and regeneration of tooth roof-of-furcation defects, which has spatial curvatures and geometrical difficulties and hardly regenerates periodontal tissues.

( K. B. M. S. Islam ),( M. S. Rahman ),( Md. Ershaduzzaman ),( M. J. F. A. Taimur ),( Hyung Kwan Jang ),( Hee Jong Song ) 한국가축위생학회 2010 韓國家畜衛生學會誌 Vol.33 No.1

An enzyme-linked immnnosorbent assay (ELISA) has been performed for the detection of the prevailing toxinotypes of Clostridium perfringens obtained from conventional culturing of intestinal contents of goats which have died of suspected enterotoxaemia. The test was found effective to detect the toxins as well as types of the organism with less time and labor. The most prevailing type of C. perfringens causing enterotoxaemia in goat was C. perfringens type D (68.75%) and followed by C. perfringens type B (25%) and C (6.25%). No C. perfringens type A was detected. This study showed an intelligible picture of prevailing toxinotypes of C. perfringens in goats in Bangladesh. The use of the ELISA for the detection of clostridial types and toxins allows the differential diagnosis of C. perfringens types A, B, C and D enterotoxaemias from samples of intestinal contents and the typing of cultures of C. perfringens.
