Reproductive Functions in Nili-Ravi Buffaloes after Short Term Treatment with Recombinant Bovine Somatotropin Hormone

Usmani, R.H.,Athar, I.H. Asian Australasian Association of Animal Productio 1997 Animal Bioscience Vol.10 No.2

Effects of short-term treatment with somidobove (recombinantly produced bovine somatotropin, BST) on estrous cyclicity and fertility were studied in dairy buffaloes. Twenty buffaloes of Nili-Ravi breed calving during the same season were assigned to either control (n=8) or treated group (n=12). The buffaloes of treated group received single infection (prolonged release) of 320 mg of somidobove on day-60 postpartum. The mean values for interval to first postpartum estrus, first service conception rate, services per conception, service period and calving interval for the treated group were 96.4 days, 66.7%, 1.70, 164 days and 473 days, respectively. The corresponding values for the control group were 92.5 days, 62.5%, 1.87, 135 days and 439 days. Means of all variables did not differ between control and treated group (p > 0.05). Three buffaloes of the control and four buffaloes of the treated group did not conceive at first service. Out of these, two buffaloes of control and one buffalo of treated group exhibited normal estrous cycles. It is concluded from these data that short term BST-treatment has no adverse effect on reproductive functions of dairy buffaloes.

A Very Simple Method for Assessing Tall Building Safety in Major Fires

Asif Usmani,Charlotte Roben,Ahmad Al-Remal 한국강구조학회 2009 International Journal of Steel Structures Vol.9 No.1

The collapse of tall buildings in a densely populated urban setting is a scenario too terrible to contemplate. Buildings are routinely designed to resist this limit state under the extreme loading conditions of high winds and earthquakes etc. However the potential of multiple floor fires to cause such a disaster remains unrecognised in the profession as no current building codes require the consideration of this type of extreme loading. Previous work by the author and his students has demonstrated that the collapse of tall buildings in multiple floor fires is a distinct possibility as the mechanisms that can cause this are easily reproduced using a non-linear finite element analysis programme. This work has been extended by the author and his students to develop a simple analytical method for systematically assessing the collapse of exterior columns of tall buildings for any given fire scenarios. This paper considerably simplifies the method developed previously to the extent that the limit state of collapse under multiple floor fires can be checked even without the need to consider any particular “design” fire and with calculations that can be performed in minutes. This is based on the assumption that in major fires that affect multiple floors, it is quite likely that a number of floors will reach a state of deflection and reduced stiffness that the main load carrying mechanism will be that of catenary action leading to destabilising pull-in forces to be exerted on exterior columns. The paper will outline all the steps that must be carried out to check if the remaining structure (columns, floors, connections etc.) will remain stable under the action of the pull-in forces. It will also provide theoretical justification and discussion for all the steps and assumptions made in the assessment. Furthermore the method will be applied to a number of examples, including that of the WTC towers to check if those buildings were safe under major fires involving multiple floors.

Inguinal Herniation of Urinary Bladder on F-18 Sodium Fluoride (NaF) PET-CT

Sharjeel Usmani,Fahad Marafi,Najeeb Ahmed,Nafisah kazem 대한핵의학회 2017 핵의학 분자영상 Vol.51 No.4

Inguinal herniation of urinary bladder is uncommon and usually an incidental finding in asymptomatic patients. In some of these patients, residual urine volume and consequently, urinary tracer activity can be higher in the herniated bladder than the native bladder, in which case interpretation can be challenging on conventional planar imaging.We describe an interesting case of physiological activity in a herniated bladder simulating a Btear-drop^. This case serves an important reminder that whilst F-18NaF PET-CT has a similar spectrum of urinary activity to conventional bone scintigraphy; morphological correlation on hybrid imaging is invaluable in ensuring the physiological nature of uptake.

Regional Precipitation Variability Associated with Zonal Movement of Indian Ocean High Pressure System

Bilal Ahmed Usmani,Saqib-Ur-Rehman,Syed Adnan Hussain,Kamran Khan,Atia Elahi 한국기상학회 2019 Asia-Pacific Journal of Atmospheric Sciences Vol.55 No.4

Several studies have linked ongoing austral winter drying conditions in southwest Western Australia (SWWA) to changes in regional and large scale sea level pressure. As the region bounded by SWWA occupies limited observation of a typical global climate model (GCM), it is not easy to infer the influence of global climate change during the drought inSWWA. In this study, we explore the relationships between early winter (May-Aug) rainfall in Kent river catchment (KRC), Southwestern Australia and Indian Ocean High Pressure system.We construct two objective indices of Indian Ocean High Pressure system (IOHPS), viz., (i) the intensity of Indian Ocean High Pressure (IOHP) and, (ii) the Indian Ocean High Longitude (IOHLN) using National Center of Environmental Prediction mean sea-level pressure (MSLP) reanalysis data. The station data of seasonal rainfall is obtained from Australian Bureau of Meteorology. A representative rainfall index for the KRC was built by averaging the seasonal rainfall three major stations for the period of 1951–2016. Significant inverse relationship is found between early wintertime precipitation in KRC, Southwestern Australia and the IOHP and IOHLN. The IOHPS accounts for more of the early winter (May–August) precipitation variation in KRC than the Southern Oscillation Index (SOI), Southern Annular mode (SAM) and Indian Ocean Dipole (IOD). Our significant findings suggest that strengthening of IOHP and zonal movement of IOHPS has a major contribution in decline of early winter precipitation in KRC.

Male and female genitalia in some Libyan species of Acrididae (Orthoptera: Acridoidea)

Mohammad Kamil USMANI 한국곤충학회 2009 Entomological Research Vol.39 No.1

A comparative study of male and female genitalia was carried out in thirty-seven Libyan species representing twenty genera of the family Acrididae. An attempt has been made to describe and illustrate the different structures, namely, epiphallus, aedeagus, subgenital plate, supra-anal plate and cerci of the male, and spermatheca, ovipositor, subgenital plate, supra-anal plate and cerci of the female, in Acridids, with an aim to discover their significance in order to make the identification of genera and species, together with other generic characters, more perfect and convenient. Distinct family characters are shield or bridge-shaped condition of epiphallus; presence or absence of dorso-lateral appendices, oval sclerites and lophi on epiphallus; divided, undivided or flexured condition of aedeagus; presence or absence of gonopore process on aedeagus; condition of apical and pre-apical diverticula of spermatheca; presence or absence of glandular pouches of Cornstock and Kellog on female subgenital plate; and rudimentary or well developed condition of egg-guide. Stable characters for separating the subfamilies are taken to be presence or absence of ancorae on epiphallus, long or short condition of aedeagal sclerites; elongate, slender or short and broad condition of ovipositor valves: presence or absence of Jannone’'s organs and setae on posterior margin of female subgenital plate; and shape of diverticula of spermatheca. Useful generic characters are shape of male subgenital plate, supra-anal plate and cerci, broad or narrow condition of bridge, presence or absence of branch of bridge connecting lophi with bridge of epiphallus; mono-, bi- or tri-lobate condition of lophi of epiphallus, length and upcurved or downcurved condition of apical valve of aedeagus, shape of posterior margin of female subgenital plate, presence of setae on the whole posterior margin or confined to lateral margins only; and toothed, tuberculate or smooth condition of ovipositor valves, length of the lateral apodeme in relation to the dorsal valves. Specific characters are shape of egg-guide of female subgenital plate, shape of ovipositor valves and apical tips, shape of male supra-anal plate and cerci, size of anterior and posterior lobes of lophi of epiphallus, size and shape of ancorae, shape of apical valves of aedeagus; and size of apical and pre-apical diverticula and presence of protuberance on pre-apical diverticulum.

Small Airways Dysfunction in Asthma: Evaluation and Management to Improve Asthma Control

Omar S Usmani 대한천식알레르기학회 2014 Allergy, Asthma & Immunology Research Vol.6 No.5

The small airways have been neglected for many years, but interest in the topic has been rekindled with recent advances in measurement techniquesto assess this region and also the ability to deliver therapeutics to the distal airways. Current levels of disease control in asthmatic patientsremain poor and there are several contributory factors including; poor treatment compliance, heterogeneity of asthma phenotypes and associatedcomorbidities. However, the proposition that we may not be targeting all the inflammation that is present throughout the whole respiratory tree mayalso be an important factor. Indeed decades ago, pathologists and physiologists clearly identified the importance of small airways dysfunction inasthmatic patients. With improved inhaler technology to deliver drug to target the whole respiratory tree and more sensitive measures to assess thedistal airways, we should certainly give greater consideration to treating the small airway region when seeing our asthmatic patients in clinic. Theaim of this review is to address the relevance of small airways dysfunction in the daily clinical management of patients with asthma. In particularthe role of small particle aerosols in the management of patients with asthma will be explored.
