The objective of this research was to compare the composition of bacterial microbiota associated with the ruminal content (RC), ruminal epithelium (RE) and faeces of Holstein dairy cows. The RC, RE and faecal samples were collected from six Holstein dairy cows when the animals were slaughtered. Community compositions of bacterial 16S rRNA genes from RC, RE and faeces were determined using a MiS...

The family of regular closed subsets of a topological space is used to introduce two concepts concerning a function f from a space X to a space Y . The first of them is the notion of f being rc-continuous. One of the established results states that a space Y is extremally disconnected if and only if each continuous function from a space X to Y is rc-continuous. The second concept studied is the...

Shoulder complaints are common in the elderly and hamper daily functioning. These complaints are often caused by tears in the muscle-tendon units of the rotator cuff (RC). The four RC muscles stabilize the shoulder joint. While some RC muscles are frequently torn in shoulder complaints others remain intact. The pathological changes in RC muscles are poorly understood. We investigated changes in...

OBJECTIVES The objective of this study is to reach a model defining factors precipitating short survival in patients with oesophageal varices and improving the understanding of such factors. Models would help to prioritize the clinical goals and intervention for saving the lives of patients. METHODS Retrospective analysis of all patients admitted to King Abdul Aziz University Hospital who had...

Comparative analysis of common essential constituents between single herbs, Ramulus cinnamomi (RC) and Herba schizonepetae (HS), and herbal pair (HP). RC – HS was performed by gas chromatography-mass spectrometry (GC-MS) combined with alternative moving window factor analysis (AMWFA) and temperatureprogrammed retention indices (PTRIs). In all, 33, 37, and 43 essential chemical components in ess...

The CP47–RC complex of photosystem II (PS II) has an antenna subunit of 16 chlorophyll a molecules attached to the reaction center (RC) at the side of its inactive branch. The X-ray structure of PS II revealed that the shortest interpigment distances between CP47 and RC are about 21 Å, which is two-three times larger than within each subunit. Such long distances may slow down the energy transfe...

Relative centricity RC values of vertices/atoms are calculated within the Distance Detour and Cluj-Distance criteria on their corresponding Shell transforms. The vertex RC distribution in a molecular graph gives atom equivalence classes, useful in interpretation of NMR spectra. Timed by vertex valences, RC provides a new index, called Centric Connectivity CC, which can be useful in the topologi...

BACKGROUND Disability of the shoulder joint is often caused by a tear in the rotator cuff (RC) muscles. Four RC muscles coordinate shoulder movement and stability, among them the supraspinatus and infraspinatus muscle which are predominantly torn. The contribution of each RC muscle to tear pathology is not fully understood. We hypothesized that muscle atrophy and fatty infiltration, features of...

The effects of somatostatin analogue RC-160 and bombesin/gastrin releasing-peptide (GRP) antagonist RC-3095 were evaluated in Copenhagen rats bearing the anaplastic, androgen-independent Dunning R3327-AT-1 prostatic adenocarcinoma. In the first experiment, RC-160 was given in the form of microcapsules releasing 60 micrograms/day/rat. RC-3095 was administered from implanted Alzet osmotic minipum...

The chloride corrosion of reinforcing steel in reinforced concrete (RC) structures is a significant reason for premature deterioration and failure of RC structures in aggressive environments such as Persian Gulf region. This is one of the most important sources of engineering and economic problems in developed countries. So, the repair and maintenance of RC structures exposed to corrosive envir...
