Abstract:
To compare the maximal rate of rise of torque (MRRT) of quadriceps femoris and adductor pollicis during voluntary and involuntary contractions, subjects performed voluntary isometric contractions as rapidly as possible over the full range of force-producing capacity. Involuntary contractions were evoked with single shocks and with trains of 10 pulses at 100 Hz at increasing voltages applied directly to the femoral and ulnar nerves. There were linear relationships between MRRT and absolute torque in both muscles during involuntary and voluntary contractions. At the same absolute torque, quadriceps femoris had a higher MRRT than adductor pollicis when both were voluntarily activated (P < 0.05). However, there was no difference in MRRT between these muscles during stimulated contractions. Compared with involuntary tetanic contractions, MRRT during voluntary contractions was the same in quadriceps femoris and was less in adductor pollicis (P < 0.05). These observations suggest that in activating some muscles, such as adductor pollicis, the central nervous system may adopt the strategy of a more gradual excitation to make the contractions more task appropriate.

Abstract:
Rapid and differential diagnosis of highly pathogenic avian influenza virus (HPAIV) subtype H5 is essential for the effective prevention and control of outbreaks caused by this pathogen. In this study, we describe a one-step multiplex real-time reverse transcription polymerase chain reaction (mRRT-PCR), using H5-, N1-, and N8-specific primers and probes, for differential detection of two HPAIVs (H5N1 and H5N8) and other H5-subtype AIVs. Using the mRRT-PCR assay, we were able to detect H5N1, H5N8, and other H5-subtype AIVs in a one-tube reaction, with high specificity; furthermore, using an in silico PCR program, we confirmed that this assay can detect nearly all H5, N1, and N8 genes of AIVs currently available in the Influenza Sequence Database. The limit of detection of the assay was determined to be as low as 100 copies/reaction for each target gene, and was comparable to limits of detection of previously reported mRRT-PCR assays. Thus, the mRRT-PCR assay described here can serve as a rapid and reliable differential diagnostic tool for the monitoring and surveillance of H5N1, H5N8, and other H5-subtype AIVs in countries where these pathogens are problematic.

Abstract:
Purpose – The purpose of this paper is to look at the recent history of proposals to tax resource rents in Australia, from Australia’s Future Tax System Report (the “Henry Tax Review”) through to the proposed Resource Super Profits Tax (“RSPT”) and then the Minerals Resource Rent Tax (“MRRT”). The process of change from Henry to the RSPT to the MRRT can best be understood in the context of the Australian Labor Party (ALP) as a capitalist workers’ party. The author argues that it is this tension in the ALP, the shift in its internal balance further towards capital and the lack of class struggle, that has seen Labor preside over what the father of rent tax in Australia, Ross Garnaut, describes as a “problematic” tax. Design/methodology/approach – Qualitative research using Marxist tools. Findings – The paper argues that the poor health of the MRRT is a consequence of the nature of the Labor Party as a capitalist workers’ party, the shifts in power and influence within its material constitution and in essence the ascendency of capital in the capitalist workers’ party. Originality/value – A very original approach to understanding the nature of the MRRT in Australia.

Abstract:
ABSTRACT Objective: The aim of this study was to evaluate the minimum residual root thickness (MRRT) of the danger zone after preflaring of the mesio-buccal (MB) canal of mandibular first molars using ProTaper, RaCe and Gates-Glidden (GG) drills as coronal shapers by cone beam computerized tomography (CBCT). Materials and Methods: In this experimental study, the initial CBCT scans of 75 MB canals of mandibular first molars were provided within 1, 2, 3 and 4 mm of the furcation level. The samples were divided into three groups. The samples of ProTaper and RaCe groups were prepared up to F2 and #25.04 as the master apical file (MAF), respectively. The coronal preparation of the samples in the GG group was done using GG drills #2, #3 and #4 and canals were prepared till MAF # 25. After obtaining the postinstrumentation images, the MRRT and the amount of removed dentin were analyzed by t-test and ANOVA statistical analyses. Results: The GG drills removed significantly more dentin than RaCe at all the sections (P < 0.05) and more than ProTaper at 3 mm from the furcation. Statistically there was no significant difference between ProTaper and RaCe groups (P > 0.05). There was no significant difference in MRRT between the groups (P > 0.05). The mean MRRT was not < 0.75 mm at all sections. Conclusion: Based on the results of this study, when an appropriate root thickness is initially present, all of the instruments that were investigated may safely be used as coronal shapers in MB canals of mandibular first molars.

Abstract:
Background: Endoscopy is required for formal diagnosis of many upper gastrointestinal (UGI) conditions including oe- sophageal cancer (OC). There is a paucity of data on endoscopy findings in East Africa as access to testing is challeng- ing for patients. We describe the findings of 10 years of UGI endoscopy in Mbale Regional Referral Hospital (MRRH).
 Method: Records of patients that underwent UGI endoscopy in MRRH, November 2009 – March 2019 were retrospective- ly analysed. Indication, macroscopic findings, histology and patient demographics were retrieved. Sub-group analyses were performed on those with a histological diagnosis of oesophageal cancer.
 Results: 833 eligible patients received single UGI procedures during the study period. Mean age was 54.8 years, range 16-93 years and 56.9% of patients were male. The main indication was dysphagia (42%) and the most common findings OC (34%) and gastritis (28%). 151 patients had histologically proven OC with a median age of 60 years and a 2:1 male to female ratio. 145/151 (96%) of samples tested revealed squamous cell carcinoma (SCC).
 Conclusion: Those undergoing endoscopy in MRRH are most commonly male patients presenting in their 5th decade with dysphagia. There is a high proportion of significant findings including gastritis, peptic ulcer disease, and oesophageal cancer.

Abstract:
Background. Increase in the number of ectopic pregnancy is attributed to increase in the incidence of pelvic infections. Chlamydia trachomatis is responsible for most of the sexually transmitted bacterial infections. If undetected and untreated, the infection can ascend to the upper genital tract and cause pelvic inflammatory disease (PID) and related sequelae (ectopic pregnancy and tubal factor infertility). Objective. To determine the association between prior Chlamydia trachomatis infection and ectopic pregnancy at Mbarara Regional Referral Hospital (MRRH). Methods. This was an unmatched case-control study carried out at MRRH involving 25 cases and 76 controls. Serological evidence of prior chlamydial infection was determined by testing for the presence of Chlamydia immunoglobulin G antibodies in their blood. Logistic regression was used to determine the association between prior Chlamydia trachomatis infection and also the factors associated with ectopic pregnancy. The significant level of <0.05 was used. Results. Chlamydia antibodies were found in 60% of patients with ectopic pregnancy and 26.3% of the controls (p=0.002). The presence of Chlamydia antibodies was associated with a fourfold risk of ectopic pregnancy. Conclusion. There was a strong association between prior Chlamydia trachomatis infection and ectopic pregnancy.

Abstract:
OBJECTIVEIn addition to the rising burden of surgical disease globally, infrastructure and human resources for health remain a great challenge for low- and middle-income countries, especially in Uganda. In this study, the authors aim to explore the trends of neurosurgical care at a regional referral hospital in Uganda and assess the long-term impact of the institutional collaboration between Mulago National Referral Hospital and Duke University.METHODSAn interrupted time series is a quasi-experimental design used to evaluate the effects of an intervention on longitudinal data. The authors applied this design to evaluate the trends in monthly mortality rates for neurosurgery patients at Mbarara Regional Referral Hospital (MRRH) from March 2013 to October 2015. They used segmented regression and autoregressive integrated moving average models for the analysis.RESULTSOver the study timeframe, MRRH experienced significant increases in referrals received (from 117 in 2013 to 211 in 2015), neurosurgery patients treated (from 337 in 2013 to 625 in 2015), and operations performed (from 61 in 2013 to 173 in 2015). Despite increasing patient volumes, the hospital achieved a significant reduction in hospital mortality during 2015 compared to prior years (p value = 0.0039).CONCLUSIONSThis interrupted time series analysis study showed improving trends of neurosurgical care in Western Uganda. There is a steady increase in volume accompanied by a sharp decrease in mortality through the years. Multiple factors are implicated in the significant increase in volume and decrease in mortality, including the addition of a part-time neurosurgeon, improvement in infrastructure, and increased experience. Further in-depth prospective studies exploring seasonality and long-term outcomes are warranted.

Abstract:
No<br>Nickel alloys including Inconel 718 are considered as challenging materials for machining. Laser beam machining could be a promising choice to deal with such materials for simple to complex machining features. The machining accuracy is mainly dependent on the rate of material removal per laser scan. Because of the involvement of many laser parameters and complexity of the machining mechanism it is not always simple to achieve machining with desired accuracy. Actual machining depth extremely varies from very low to aggressively high values with reference to the designed depth. Thus, a research is needed to be carried out to control the process parameters to get actual material removal rate (MRRact) equals to the theoretical material removal rate (MRRth) with minimum surface roughness (SR) of the machined surfaces. In this study, five important laser parameters have been used to investigate their effects on MRR and SR. Statistical analysis are performed to identify the significant parameters with their strength of effects. Mathematical models have been developed and validated to predict the machining responses. Optimal set of laser parameters have also been proposed and confirmed to achieve the actual MRR close to the designed MRR (MRR% = 100.1%) with minimum surface roughness (Ra = 2.67 µm).<br>The authors extend their appreciation to the Deanship of Scientific Research at King Saud University for funding this work through research group number RG-1440-026.
