Abstract
BACKGROUND The current pandemic has reduced access to safe, monitored physical activity (PA) programs for persons with spinal cord injury (SCI). The use of telerehabilitation has the potential for continuing activity engagement without risking virus exposure. The present study evaluates the feasibility and efficacy of an online group-based PA program for persons with SCI. METHODS This preliminary pre-post study delivered an online group-based PA program to persons with SCI. The program consisted of 1-hour sessions twice weekly for six weeks. Online PA satisfaction questionnaires were assessed at post-treatment. Psychosocial subscales from the NeuroQOL-SF were assessed. RESULTS Participants were adult females between 3 and 32 years post-injury, 1 tetraplegic and 3 paraplegics (n = 4). All participants were highly satisfied with the online instruction, overall content, and videoconferencing platform. Participants stated that the online program was beneficial for their overall physical and psychosocial wellbeing. The program resulted in improvement in anxiety and satisfaction with social roles and activities. CONCLUSION The current pilot study demonstrates the acceptability and limited efficacy of an online PA program for those with SCI. The program resulted in improved overall perceived wellbeing and satisfaction with social roles and activities. These results have important implications for the clinical implementation of online PA programs in a hospital and community setting.

Abstract
WHAT IS KNOWN AND OBJECTIVE Incretin-based glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and dipeptidyl peptidase-4 (DPP-4) inhibitor therapies provide glycaemic control with reduced risks associated with weight gain or hypoglycaemia. Incretin therapies are compared with their mechanisms of action, effects on haemoglobin A(1C) (HbA(1C)), fasting plasma glucose (FPG), post-prandial glucose (PPG), body weight, β-cell function, cardiovascular biomarkers and in their safety profiles to aid clinicians in the selection of individualized pharmacotherapy for patients with type 2 diabetes. METHODS Relevant articles for a systematic review were identified through PubMed. Randomized, head-to-head comparison studies among incretin therapies were identified and included in the review. Additionally, randomized, controlled monotherapy and combination therapy studies examining glycaemic and extraglycaemic effects of individual incretin therapies from 2007 to 2011 were reviewed. RESULTS AND DISCUSSION Glucagon-like peptide-1 receptor agonists are generally preferred over DPP-4 inhibitors because of their greater effectiveness in reducing HbA(1C) , FPG and PPG excursions, and greater weight loss potentiation. As a monotherapy option, longer-acting GLP-1 RAs, including liraglutide and exenatide once-weekly, may be preferred at higher HbA(1C) because of their more pronounced effects on FPG. At lower/near normal HbA(1C) , a short-acting GLP-1 RA, such as exenatide twice-daily, may be a better choice as its effects are more pronounced with PPG. Ideal patients or patient situations for DPP-4 inhibitors include patients who need minimal reduction in HbA(1C,) elderly patients, patients who are unwilling or unable to take an injectable agent, when GLP-1 RAs are contraindicated or when the patient will not benefit from weight loss. Treatment benefits common to all incretin-based therapies include minimal hypoglycaemia risk, potential preservation of β-cell function and effective targeting of multiple organs underlying type 2 diabetes and of comorbidities commonly associated with type 2 diabetes, such as obesity and hypertension. WHAT IS NEW AND CONCLUSION Key differences in mechanisms of action and in glycaemic and extra-glycaemic treatment outcomes exist among incretin therapies, both within the GLP-1 RA class, and between GLP-1 RAs and DPP-4 inhibitors. Clinical judgment acknowledging important differences among incretin therapies and treatment-related patient characteristics will aid in the selection of the appropriate incretin agent for individualized pharmacotherapy.

Abstract
WHAT IS KNOWN AND OBJECTIVE Type 2 diabetes mellitus (T2DM) is a progressive multisystem disease, and less than half the population with T2DM has achieved the recommended glycosylated haemoglobin A1c goal. We aim to present key points to consider when selecting pharmacotherapy for the management of T2DM. The selection of pharmacotherapy is discussed within the context of the underlying pathophysiology of T2DM, currently available treatment options highlighting newer agents and current clinical guidelines. COMMENT Combination therapy regimens that target the multiple organ systems involved in the pathophysiology of T2DM can be developed based on the mechanism of action (MOA) of each class of agents. We compare the pathophysiology of T2DM with the MOA of the currently available non-insulin therapeutic options. WHAT IS NEW AND CONCLUSION Combination therapy that efficiently and effectively targets multiorgan correction with the least risk for serious adverse events, such as hypoglycaemia and drug interactions, is needed when initial treatment fails to achieve the desired clinical outcomes. Newer agents, now incorporated in treatment guidelines, increase the range of options available to the clinician.

Abstract
Increasing quantities of atmospheric anthropogenic fixed nitrogen entering the open ocean could account for up to about a third of the ocean's external (nonrecycled) nitrogen supply and up to approximately 3% of the annual new marine biological production, approximately 0.3 petagram of carbon per year. This input could account for the production of up to approximately 1.6 teragrams of nitrous oxide (N2O) per year. Although approximately 10% of the ocean's drawdown of atmospheric anthropogenic carbon dioxide may result from this atmospheric nitrogen fertilization, leading to a decrease in radiative forcing, up to about two-thirds of this amount may be offset by the increase in N2O emissions. The effects of increasing atmospheric nitrogen deposition are expected to continue to grow in the future.

Abstract
Published observations of organic nitrogen (N) compounds in precipitation go back almost a century. Several different methods have been used to measure both the total and ionic concentrations of N. There is therefore some uncertainty as to whether reported "organic N" is real, or simply the result of uncertainties in chemical analyses or inadequate sampling methods. We found that the materials from which the collector was made (polypropylene, steel, or glass) had no significant effect on the composition of dissolved organic N (DON). The use of a biocide was found to be very important during sampling and storage of samples before analysis. We set up a network of seven collectors across the U.K., from the Cairngorms to Dorset, all operating to the same protocol, and including a biocide. Samples were analysed centrally, using proven methods. Over 6 months, organic N contributed about 20% to the total N in U.K. precipitation, but with a large variation across the country. This means that current estimates of wet deposited N to the U.K., which are based only on the ammonium and nitrate concentrations, are too small. Organic N is not an artefact, but a real problem that needs to be addressed.

Abstract
Deterministic and stochastic models are used to examine the evolution of anthelmintic resistance among trichostrongylid parasites of domestic ruminants. We find that the relative selection pressures exerted by chemoprophylactic (preventive) control strategies, chemotherapeutic (salvage) control strategies, and regimens involving "under-dosing" are critically dependent on a variety of host and parasite parameters (particularly host immunity and grazing behaviour, parasite fecundity, and the survival of the free-living stages on the pasture). Chemoprophylactic strategies are not necessarily more likely to exert a stronger selection pressure than chemotherapeutic strategies. Similarly, as one reduces dosage levels, there is a range of dose levels where under-dosing promotes resistance and a range of dose levels where under-dosing impedes resistance. The most dangerous dose is either that necessary to kill all the susceptible homozygotes, or that necessary to kill all the susceptible homozygotes and all the heterozygotes. Which one prevails depends upon model parameters. The stochastic formulation indicates that spatial heterogeneity in transmission may be a significant force in promoting the spread of resistant genotypes--at least when infection is at low levels.

Abstract
We investigated the therapeutic potential of an acid-resistant fungal lipase prepared from Aspergillus niger. We first demonstrated in vitro that it had a wide pH optimum of 2.5-5.5 and was resistant to pepsin and trypsin. We gave the enzyme or matching placebo in random order by mouth with a fatty meal to 10 adult patients with pancreatic steatorrhoea due to cystic fibrosis (CF) and sampled gastric contents for the following 2 h. Mean acid-resistant lipase activity was 330 nmol/ml/min free fatty acid released on placebo, compared with 896 nmol/ml/min on fungal lipase (p = 0.006 for area under the curve). We compared this lipase's clinical efficacy with that of two conventional pancreatin microsphere formulations in an open randomised crossover fat-balance study in 10 similar patients. Each preparation was given for 2 weeks, and a fat-balance study, using a faecal recovery marker, was performed on the final 3 days; a period without treatment was also included. The fungal lipase had no effect on faecal wet weight or on the coefficient of fat absorption (59.0% vs. 52.3%; NS) in comparison with placebo. The established enteric-coated microsphere preparation (Creon) produced a significant reduction in faecal wet weight and improvement in coefficient of fat absorption (81.4% vs. 52.3%; p less than 0.01) in comparison with placebo. The newer microsphere preparation (Pancrex M) was also effective, but perhaps less so than Creon; there were no significant differences between the two preparations.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
DNA probes were produced for the detection and identification of 4 cultivable species of oral spirochetes, Treponema denticola, Treponema socranskii, Treponema vincentii and Treponema pectinovorum. To obtain probe sequences, chromosomal DNA, isolated from representative strains within each species, was cloned in Escherichia coli K-12. Cloned DNA fragments were screened for the ability to hybridize to DNA only from homologous strains. Several such fragments were identified and shown to be specific when tested against a series of DNAs from gram-negative and gram-positive oral bacteria. The selected probe sequences were semi-conserved within strains of T. denticola and T. socranskii such that restriction fragment length polymorphism (RFLP) was observed. In the case of T. socranskii, RFLP was useful in distinguishing between the 3 known subspecies. Chromosomal DNA fragments from 2 strains of T. vincentii failed to cross-hybridize, under stringent conditions, to genomic DNA from each of these strains. The hybridization probes were suitable for the identification of clinical isolates of T. denticola and could be used to detect the presence of individual Treponema species in mixed cultures. On this basis, the probes were used successfully to detect T. denticola in uncultured plaque samples.

Abstract
Although Actinobacillus actinomycetemcomitans has been recognized as a primary etiological agent in localized juvenile periodontitis, questions remain concerning the source of infection, mode of transmission, and relative virulence of strains. DNA fingerprinting analysis, using a randomly cloned chromosomal DNA fragment as a probe, revealed that previously characterized strains of A. actinomycetemcomitans displayed significant restriction site heterogeneity which could be applied to the typing of clinical isolates of this bacterium such that individual strains or variants could be traced within subjects from localized juvenile periodontitis families. Hybridization data derived from an analysis of bacterial isolates obtained from families participating in an ongoing longitudinal study of the disease showed that a single individual could be infected with more than one strain or variant of A. actinomycetemcomitans and that various members of the same family could harbor different strains or variants of the bacterium. In several cases the clinical isolates were matched to characterized laboratory strains by comparing hybridization patterns generated by digestion of the DNA with several restriction enzymes in independent reactions. Thus, probe-specific DNA fingerprinting of A. actinomycetemcomitans will permit us to determine if particular strains or variants are frequently associated with sites of periodontal destruction. Attention could then be focused on determining the virulence properties of those strains or variants that have in vivo significance.

Abstract
Moyamoya disease was diagnosed as the cause of cerebral infarction in eight young adults (seven women, one man), aged 17-40 (mean 33) years. All had angiographic abnormalities characteristic of moyamoya disease. Single-photon emission tomography showed bilateral carotid circulation hypoperfusion and posterior circulation hyperemia in all seven patients with regional cerebral blood flow studies. All seven women had used oral contraceptives before cerebral infarction. Four patients were treated medically; one died of a second cerebral infarction 9 months after diagnosis. Four patients underwent superficial temporal-to-middle cerebral artery anastomosis; they did well. Moyamoya disease should be included in the differential diagnosis of cerebral infarction as well as intracranial hemorrhage in young adults, particularly women. A possible relation between moyamoya disease and oral contraceptive use deserves investigation.

Abstract
A 55-year-old right-handed man (patient DRB) had a major amnesic syndrome following extensive bilateral damage to the temporal lobe and basal forebrain, caused by herpes simplex encephalitis. His amnesia was both anterograde and retrograde. The retrograde amnesia spanned the five decades of his life, sparing only generic (semantic) material and shreds of previous experiences devoid of appropriate temporal and spatial placement. The anterograde amnesia encompassed both generic (semantic) and contextual (episodic) material. With the exception of preserved learning of a visuomotor skill, the patient did not show acquisition of any new information since his illness in 1975. Elementary perceptual, intellectual, and linguistic abilities remained intact. Because several anatomic and behavioral characteristics of this case are different from those of previously reported cases of amnesia, they may provide new insight into the neuroanatomic substrate of human memory.

Abstract
Nine achondroplastic dwafts were studied with computerized tomography, skull and cervical spine films, and psychometric testing. All had large ventricles that ranged from the top limits of normal to severe hydrocephalus. Three had enlarged cortical sulci. Skull and cervical spine films were typical for achondroplasia, but in addition significant asymmetry of the petrous ridge was noted. Psychometric testing disclosed generally average intelligence quotients which fell below the expected performance level in each case. These findings may be explained on the basis of the abnormal endochondral bone formation found in achondroplasia.
