ninety red sokoto bucks were used to assess the relationship between body, testicular and epididymal measurements in three age groups (group 1: 7-12 months; group 2: between 1 and 2 years and group 3: older than 2 years). the effect of age on body and testicular / epididymal measurements was analyzed. a predictive model was developed for each of the testicular / epididymal measurements using li...

BACKGROUND Various strains of Bacillus thuringiensis (Bt) have been found to produce parasporal proteins that are cytotoxic to human cancer cells. This study aims to establish the binding affinity of purified Bt 18 toxin for CEM-SS (T lymphoblastic leukaemia cell line), to determine if competition exists between the toxin and commercial anticancer drugs for the binding site on CEM-SS and to loc...

The use of Bacillus thuringiensis as a biopesticide is a viable alternative for insect control since the insecticidal Cry proteins produced by these bacteria are highly specific; harmless to humans, vertebrates, and plants; and completely biodegradable. In addition to Cry proteins, B. thuringiensis produces a number of extracellular compounds, including S-layer proteins (SLP), that contribute t...

Bacillus thuringiensis strains are well known for the production of insecticidal proteins upon sporulation and these proteins are deposited in parasporal crystalline inclusions. The majority of these insect-specific toxins exhibit three domains in the mature toxin sequence. However, other Cry toxins are structurally and evolutionarily unrelated to this three-domain family and little is known of...

introduction: foreign bodies in the upper aerodigestive tract often get lost following inappropriate attempts at removal. children may present late with localized infection, posing a challenge to the otolaryngologists in a referral set-up in diagnosing and retrieving such foreign bodies.   case report: a two-year-old boy presented with refractory purulent rhinorrhea and intermittent low-grade f...

introduction: the diagnosis of foreign bodies in the upper aerodigestive tract is usually straightforward but sometimes it can be delayed or the location of esophageal and upper airway foreign bodies can be mistakenly interchanged.  case report: we present two interesting cases that caused diagnostic challenges which could have led to serious complications if a greater delay in diagnosis had oc...

background: the over-expression of recombinant proteins in large amount is important for production of therapeutic proteins and structural study. there are several systems for expression of recombinant proteins. one of the most relevant expression systems is escherichia coli (e. coli). although this organism has many advantages, most of recombinant proteins expressed in e. coli hosts form inclu...

background : foreign body aspiration is a common medical emergency among children that can lead to lethal complications especially in neglected or misdiagnosed cases. case report: this article is a report of a 15-month-old child who aspirated food materials and after chocking crisis, she presented with unspecific respiratory symptoms and treated for respiratory tract infections. after five days...

discussion this case has two unusual features. first, it is difficult for a foreign body to reach the urinary bladder in males. second, the presented case was left unattended for two whole weeks. introduction urinary bladder is the most common site for foreign body in the urinary tract. self insertion of a long object into the bladder is very difficult in males. we present a case of self-insert...
