Non-starch polysaccharides in beer and brewing: A review of their occurrence and significance.

It has become apparent that beer (both alcoholic and nonalcoholic) contains appreciable amounts of non-starch polysaccharides, a broad subgroup of dietary fiber. It is worth noting that the occurrence of non-starch polysaccharides in alcoholic beer does not imply this should be consumed as a source of nutrition. But the popularity of nonalcoholic beer is growing, and the lessons learnt from non-starch polysaccharides in brewing can be largely translated to nonalcoholic beer.

Improving Diabetes Care: A Fijian Diabetes Service Improvement Study.

Background: Achieving good outcomes in type 2 diabetes mellitus patients' needs a decent integrated care service with access to resources. The Fiji Islands has one of the highest rates of diabetes disease burden and has available resources to alleviate the diabetic disease pandemic in its population, yet patient outcomes are getting worse. We hypothesize that a dysfunction in health-care delivery system may be accentuating the diabetic disease process; therefore, this service evaluation study was conducted to provide insight into the management of T2DM in a secondary care clinic setting.

Salivary creatinine as a diagnostic tool for evaluating patients with chronic kidney disease.

Background: Preliminary studies have shown the potential use of salivary creatinine concentration in the diagnosis of chronic kidney disease (CKD). For saliva to replace serum as a diagnostic tool, studies must be done to determine its effectiveness in the diagnosis and staging of CKD. The aim of the present study was to evaluate the use of salivary creatinine as a safe and non-invasive alternative for identifying patients with CKD.

Retrospective Chart Review of Skin-to-Skin Contact in the Operating Room and Administration of Analgesic and Anxiolytic Medication to Women After Cesarean Birth.

Transporting a newborn out of the operating room after cesarean birth can contribute to maternal awareness of discomfort, anxiety, and the need for administration of analgesics and anxiolytics for relief. This retrospective study analyzed the association between skin-to-skin contact in the operating room and administration of analgesics and anxiolytics to women in the operating and recovery rooms after cesarean birth. Our results indicated a trend toward decreased medication administration for women who experienced skin-to-skin contact and add to evidence supporting the incorporation of skin-to-skin contact in the operating room as the standard of care for cesarean birth.

Craniofacial manifestations in osteogenesis imperfecta type III in South Africa.

Objectives: Osteogenesis imperfecta type III (OMIM 259420) is a severe autosomal recessive disorder. Affected individuals have multiple fractures, develop limb deformities with spinal malalignment and stunted stature.

Materials And Methods: The frequency of Osteogenesis imperfecta type III (OI III) is relatively high in the indigenous Black African population of South Africa.

Association between antral follicle count and reproductive measures in New Zealand lactating dairy cows maintained in a pasture-based production system.

The antral follicle count (AFC) in cattle is consistent throughout the estrous cycle of individual cows, and cows with a lower AFC have lower fertility. We assessed the AFC at random stages of the estrous cycle, examined the correlation between AFC classifications, and determined the relationship between the most rapid and practical laboratory-based AFC classification (AFC of follicles of ≥ 2 mm in diameter) and fertility measures in New Zealand lactating dairy cows. Cows detected in estrus (n = 202) or not (n = 239) during the first 4 weeks of the breeding season were subjected to ultrasonography and classified as having a high, medium, or low AFC at the time of scanning (on-site classification).

Is human immunodeficiency virus (HIV) stage an independent risk factor for altering the periodontal status of HIV-positive patients? A South African study.

Background: The immunosuppresion in HIV patients makes them highly susceptible to microbial infections. The aim of the study was to establish whether HIV stage (as depicted by CD4+ T lymphocyte counts) could independently be associated with periodontal status (as revealed by the measurement of clinical indices).

Methods: One hundred and twenty HIV-infected patients attending an infectious diseases clinic in the Western Cape, South Africa were included in the study.

The imaging characteristics of odontogenic myxoma and a comparison of three different imaging modalities.

Objective: To report the imaging characteristics of odontogenic myxoma (OM) and compare the different imaging modalities used.

Study Design: The radiological images of 33 OM cases were retrospectively analyzed. The radiographs were severally examined to describe the features of OM as seen on conventional radiographs (CRs), computed tomography (CT) scans, and magnetic resonance images (MRIs).

Cleidocranial dysplasia: a review of the dental, historical, and practical implications with an overview of the South African experience.

Cleidocranial dysplasia (CCD) is an uncommon but well-known genetic skeletal condition. Several hundred affected persons are members of a large extended family in the Cape Town Mixed Ancestry community of South Africa. The clinical manifestations are often innocuous, but hyperdontia and other developmental abnormalities of the teeth are a major feature and may require special dental management.

Palatal ulceration as the first sign of pulmonary tuberculosis: a case report.

Tuberculosis (TB) is one of the leading casues of morbidity and death in a number of countries worldwide. A healthy 42-year-old patient presented with a chronic palatal ulcer that was not responsive to routine antibiotic treatment. A biopsy and further systemic investigation revealed a diagnosis of TB.

Fibrodysplasia ossificans progressiva (FOP) in South Africa: dental implications in 5 cases.

Fibrodysplasia ossificans progressiva (FOP) is a severe genetic disorder in which progressive ossification of subcutaneous tissues leads to immobility and profound physical handicap. Dental management of affected persons may be constrained by impaired mobility of the temporomandibular joints. Equally, the traumatic aspects of dental intervention can exacerbate the ossification process.

Alveolar ridge preservation using leukocyte and platelet-rich fibrin: a report of a case.

In order for a dental implant to be restored optimally, it must be placed in an ideal anatomic position. However, this is not always possible, since physiological wound healing after tooth removal, often results in hard and soft tissue changes which ultimately compromises ideal implant placement. With the aim of minimising the need for tissue augmentation, several alveolar ridge preservation (ARP) techniques have been developed.

Observing supernova 1987A with the refurbished Hubble Space Telescope.

Observations with the Hubble Space Telescope (HST), conducted since 1990, now offer an unprecedented glimpse into fast astrophysical shocks in the young remnant of supernova 1987A. Comparing observations taken in 2010 with the use of the refurbished instruments on HST with data taken in 2004, just before the Space Telescope Imaging Spectrograph failed, we find that the Lyα and Hα lines from shock emission continue to brighten, whereas their maximum velocities continue to decrease. We observe broad, blueshifted Lyα, which we attribute to resonant scattering of photons emitted from hot spots on the equatorial ring.

Klippel-Trenaunay-Weber syndrome: orodental manifestations and management considerations.

Klippel-Trenaunay-Weber syndrome is characterized by a triad of features, namely, vascular nevi, venous varicosities, and hyperplasia of hard and soft tissues in the affected area. Involvement of the orofacial region is uncommon, but nevertheless, a wide range of orofacial abnormalities may necessitate specialized dental and anesthesia management. We have documented the manifestations in 2 affected persons, outlined the nosology, reviewed the literature, and tabulated craniofacial anomalies and orodental complications.

Effects of active immunization against growth differentiation factor 9 and/or bone morphogenetic protein 15 on ovarian function in cattle.

Growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) are essential for ovarian follicular growth in sheep, whereas only GDF9 is essential in mice suggesting that the roles of these oocyte-derived growth factors differ among species. At present, however, there is only limited information on the action of BMP15 and GDF9 in other species. Thus, the aim of this experiment was to determine the effect of neutralizing GDF9 and/or BMP15 in vivo on ovarian follicular development and ovulation rate in cattle through active immunization using the mature regions of the proteins or peptides from the N-terminal area of mature regions.

Carbohydrate utilization and the lager yeast transcriptome during brewery fermentation.

The fermentable carbohydrate composition of wort and the manner in which it is utilized by yeast during brewery fermentation have a direct influence on fermentation efficiency and quality of the final product. In this study the response of a brewing yeast strain to changes in wort fermentable carbohydrate concentration and composition during full-scale (3275 hl) brewery fermentation was investigated by measuring transcriptome changes with the aid of oligonucleotide-based DNA arrays. Up to 74% of the detectable genes showed a significant (p View Article and Find Full Text PDF

Lennox gastaut syndrome, review of the literature and a case report.

Background: Lennox-Gastaut syndrome (LGS) is a severe form of childhood epilepsy that is defined by generalized multiple type seizures, slowness of intellectual growth, and a specific EEG disturbance. Children affected might previously have infantile spasms or underlying brain disorder but etiology can be idiopathic. In South Africa, the incidence of secondary epilepsy is higher than what is found in developed countries resulting in higher incidence of the disease.

The oxidative stress response of a lager brewing yeast strain during industrial propagation and fermentation.

Commercial brewing yeast strains are exposed to a number of potential stresses including oxidative stress. The aim of this investigation was to measure the physiological and transcriptional changes of yeast cells during full-scale industrial brewing processes with a view to determining the environmental factors influencing the cell's oxidative stress response. Cellular antioxidant levels and genome-wide transcriptional changes were monitored throughout an industrial propagation and fermentation.

Patterns of expression of messenger RNAs encoding GDF9, BMP15, TGFBR1, BMPR1B, and BMPR2 during follicular development and characterization of ovarian follicular populations in ewes carrying the Woodlands FecX2W mutation.

Woodlands sheep have a putative genetic mutation (FecX2(W)) that increases ovulation rate. At present, the identity of FecX2(W) is unknown. The trait does not appear to be due to the previously described mutations in bone morphogenetic protein 15 (BMP15), growth differentiation factor 9 (GDF9), or bone morphogenetic protein receptor type 1B (BMPR1B) that affect ovulation rate in sheep.

Evaluating the process of polishing borosilicate glass capillaries used for fabrication of in-vitro fertilization (iVF) micro-pipettes.

In this paper we investigate a number of gas flames for fire polishing borosilicate glass capillaries used in the manufacturing of IVF micro-pipettes. Hydrofluoric acid (HF) was also used as an alternative to finish the pipette end. Glass micro tools in the IVF industry are drawn from hollow glass capillaries of diameter 1 mm.

Yeast responses to stresses associated with industrial brewery handling.

During brewery handling, production strains of yeast must respond to fluctuations in dissolved oxygen concentration, pH, osmolarity, ethanol concentration, nutrient supply and temperature. Fermentation performance of brewing yeast strains is dependent on their ability to adapt to these changes, particularly during batch brewery fermentation which involves the recycling (repitching) of a single yeast culture (slurry) over a number of fermentations (generations). Modern practices, such as the use of high-gravity worts and preparation of dried yeast for use as an inoculum, have increased the magnitude of the stresses to which the cell is subjected.

More men than women make mucosal IgA antibodies to Human papillomavirus type 16 (HPV-16) and HPV-18: a study of oral HPV and oral HPV antibodies in a normal healthy population.

Background: We have previously shown the high prevalence of oral anti-human papillomavirus type 16 (HPV-16) antibodies in women with HPV-associated cervical neoplasia. It was postulated that the HPV antibodies were initiated after HPV antigenic stimulation at the cervix via the common mucosal immune system. The present study aimed to further evaluate the effectiveness of oral fluid testing for detecting the mucosal humoral response to HPV infection and to advance our limited understanding of the immune response to HPV.

Meat and Livestock Association Plenary Lecture 2005. Oocyte signalling molecules and their effects on reproduction in ruminants.

Sheep (Ovis aries) are a highly diverse species, with more than 900 different breeds that vary significantly in their physiological characteristics, including ovulation rate and fecundity. From examination of inherited patterns of ovulation rate, several breeds have been identified with point mutations in two growth factor genes that are expressed in oocytes. Currently, five different point mutations have been identified in the BMP15 (GDF9b) gene and one in GDF9.

Residual function in peripheral nerve stumps of amputees: implications for neural control of artificial limbs.

Purpose: It is not known whether motor and sensory pathways associated with a missing or denervated limb remain functionally intact over periods of many months or years after amputation or chronic peripheral nerve transection injury. We examined the extent to which activity on chronically severed motor nerve fibers could be controlled by human amputees and whether distally referred tactile and proprioceptive sensations could be induced by stimulation of sensory axons in the nerve stumps.

Methods: Amputees undergoing elective stump procedures were invited to participate in this study.
