COMPARATIVE PERFORMANCE OF THE INDIGENOUS AND EXOTIC SOWS IN NIGERIA
Authors: Adebambo O. A. , Dettmers A. E. 
Published: March 2021

THE indigenous sow of Nigeria which is about half the size of the exotic large white, Landrace or crossbred pigs at maturity (60 vs 128-141kg) has an average milk yield of 75kg as compared to 130 148kg of the exotic breeds during an eight week lactation. Peak production was reached between the third and fifth weeks of lactation by the impor ted, while the native sow showed quite a slight peak but with greater persistency. For all geno types compared, milk yield was lower in the dry season (P< 0.05) than in the wet season (123 vs 134kg) and higher for sows (P < 0.05) than for gilts (135 vs 121kg). With an average litter size of 5-8 pigs, available milk per piglet was between 16kg in the Indigenous SOW and 28kg in the Landrace soWS (P < 0.05) and a significant difference (P < 0.05) in effi ciency of milk utilization by the piglets in the range of Crossbred, followed by the purebreds, the indigenous being the least efficient in relation to unit metabolic size Milk production did not differ among the genotypes. The high positive correlations (P < 0.05) between milk yield and body weight at farrow and the unit metablie size as well as between milk intake and litter size might serve as a useful tool in selection for the Nigerian Indigenous pigs as the higher body weight tend to be correlated to a higher milk yield and a correspondingly large litter size.
ENERGY REQUIREMENTS OF INDIGENOUS AND EXOTIC LACTATING COWS IN A HUMID, TROPICAL ENVIRONMENT
Authors: Adebowale E.A. 
Published: March 2021

Owing to paucity of information on the energy requirements of lactating cows in a humid tropical environment, a study using twelve lactating cows and Six steers was conducted at Ibadan, Nigeria. Animals weighing between 355 and 445kg were used in metabolism studies with four cows and two steers from each of the White Fulani (WF), German Brown (GB) and Friesian (F) breeds. Metabolizable energy (ME) required for maintenance ranged from 0.37 for the Friesiun, 0.41 for the German Brown to 0.44 MJ/day/W0.734kg for the White Fulani animals. Since the regressions were parallel and coincident, pooled figures of 0.41MJ ME/day/W0.734kg or 0.31MJ net energy ME/day/wk0.734g for all breeds in a tropical environment could be used. Efficiency of utilization of metabolizable energy for milk synthesis was about 31%. while a large variation was obtained for efficiency of utilization of the diets fed forage (18%), low concentrate (32%, and high concentrate (44%). Lactating cows required lower maintenance but higher productive metabolizable energy than those in the temperate regions.

Authors: Rosyidi Muhammad Iqbal 
Published: March 2021

As a world-class tourism destination, Indonesia is facing challenges in providing competent tourism human capital. Currently, the majority of tourism labor in Indonesia are low levels of education and only a few of them are graduated from higher education. Empirically, numerous studies suggest that many graduates from various tourism schools in several countries preferred to not opt for the tourism careers. This study aims to discover and analyze the perceptions and attitudes of final year students majoring in tourism and hospitality in Indonesia to pursue a career in the tourism industry. Using online distributed questionnaire through snowball sampling method, this study obtained 422 completed responses of tourism and hospitality undergraduates from Jakarta, Bandung, Lombok, Makassar, Palembang, Bali, Yogyakarta, Surakarta, and Batam. The collected data then analyzed by Importance Performance Analysis and cross-tabulation analysis. This study found that the career advancement and salaries were two factors in the industry considered as important factors but got a bad perception. However, the nature of work of tourism industry which offering enjoyable and fun environment are considered important and earned positive perception. This study also presents some impli­cations, mainly for the tourism industry in Indonesia.

AbstractIntroductionWhether depression is a prodromal phase or risk factor for dementia is under debate. We aimed to unveil the nature of depression–dementia association by looking into the time window of depression occurrence.MethodsDementia‐free twins (n = 41,727) from the Swedish Twin Registry were followed‐up for 18 years. Data were analyzed using generalized estimating equation (GEE) for all individuals and conditional logistic regression for co‐twin matched pairs.ResultsIn the GEE model, multi‐adjusted odds ratios (ORs; 95% confidence intervals [CIs]) of dementia were 1.46 (1.09–1.95) for mid‐life, 2.16 (1.82–2.56) for late‐life, 2.24 (1.49–3.36) for mid‐ to late‐life, and 2.65 (1.17–5.98) for lifelong depression. The ORs in conditional logistic regression and in GEE did not differ significantly (P = 0.60). Education ≥8 years attenuated dementia risk associated with mid‐life depression.DiscussionNot only late‐life depression, but also mid‐life depression is associated with dementia. Genetic and early‐life environmental factors could not account for this association. Education ≥8 years might buffer the impact of mid‐life depression on dementia.

AbstractBackgroundSarcomatoid renal cell carcinoma (SRCC) is associated with poor prognosis. Although there is no standard treatment for SRCC, recent studies have reported the effectiveness of immune checkpoint inhibitors.CaseAn 82‐year‐old Japanese man presented to our hospital with an incidental right renal tumor. Abdominal computed tomography (CT) showed an exophytic tumor in the right kidney with suspected right iliopsoas muscle invasion. Laparoscopic right radical nephrectomy was performed. Histopathological diagnosis revealed a clear cell RCC with a spindle cell carcinoma component. CT performed 3 months after surgery revealed multiple bilateral lung metastases and local recurrence. Although the patient received tyrosine‐kinase inhibitors for treating multiple metastases, the lung metastases continued to gradually increase, and peritonitis carcinomatosis was observed. Thus, the patient was intravenously administered nivolumab once every 2 weeks. After nivolumab administration, lung metastases, local recurrence, and peritonitis carcinomatosis gradually reduced. After 20 months of nivolumab treatment, the patient achieved a complete response of multiple metastases on CT.ConclusionNivolumab may be used as a treatment option for sarcomatoid renal cell carcinoma with multiple metastases.
One‐pot emulsion templating for simultaneous hydrothermal carbonization and hydrogel synthesis: porous structures, nitrogen contents and activation
Authors: Horowitz Adi , Shaul Gil , Silverstein Michael S 
Published: March 2021

AbstractPorous carbons are of interest for a wide range of advanced‐technology ‘green’ energy applications including fuel cells, hydrogen storage, supercapacitors and batteries. Functional groups, heteroatoms and a more accessible hierarchical porous structure would be advantageous for many of these applications. This paper describes the generation of carbonaceous monoliths with hierarchically porous structures and nitrogen functionalities by using a one‐pot, simultaneous combination of hydrogel synthesis and hydrothermal carbonization (HTC) that involves templating within high internal phase emulsions (HIPEs). A carbon monolith with a density of 0.058 g cm−3, a highly interconnected, bimodal porous structure and an apparent specific surface area (SBET) of 101 m2 g−1 was produced by carbonizing a HTC monolith based on 2‐hydroxyethyl methacrylate (HEMA) at 450 °C. SBET of 1540 m2 g−1 was produced through subsequent chemical activation with ZnCl2 at 700 °C, but the overall residual mass (Rm) was only 9 wt%. Direct chemical activation of the HTC monolith, on the other hand, generated SBET of 1250 m2 g−1 and an overall Rm of 28 wt%, corresponding to a higher apparent surface area per mass of HTC monolith. Carbon monoliths with N/C ratios of 0.09 and 0.07 were achieved using nitrogen‐rich monomers (acrylamide and vinylimidazole, respectively) as compared to the HEMA‐based carbon monolith with an N/C ratio of 0.03. This work demonstrates that the hierarchically porous structures and the chemical structures of these highly porous monoliths can be fine‐tuned by modifying the HIPE composition and/or the processing conditions. © 2021 Society of Industrial Chemistry.
How to choose a time zero for patients in external control arms
Authors: Backenroth Daniel 
Published: March 2021

AbstractWhen a sponsor carries out a single‐arm trial of a novel oncology compound, it may wish to assess the efficacy of the compound via comparison of overall survival to an external control arm, constructed using patients included in some retrospective registry. If efficacy of the novel compound is compared to efficacy of physician's choice of chemotherapy, patients in the retrospective registry might qualify for inclusion in the external control arm at multiple different points in time, when they receive different chemotherapy treatments. For example, a patient might qualify at the start of their second, third and fourth lines of therapy. From the start of which line of therapy should this patient's survival be compared to survival of participants in the single‐arm trial? Some sponsors have elected to include patients in the external control arm from the last available line of therapy in the retrospective database. Another possibility is to randomly select a line of therapy for each external control arm patient from among those available. In this paper, we show, via probabilistic arguments and also via simulation based on real data, that both of these methods give rise to a bias in favor of the single‐arm trial. We further show that this bias can be avoided by instead including external control arm patients multiple times in the external control arm, once for each time they receive qualifying treatment.
Effects of physicochemical factors on PAH degradation by Planomicrobium alkanoclasticum

Published: March 2021

AbstractPolycyclic aromatic hydrocarbons (PAHs) are environmental pollutants that are mutagenic, carcinogenic, and toxic to living organisms. Here, the ability and effectiveness of selected bacteria isolated from an oil‐contaminated area in biodegrading PAHs were evaluated, and the optimal conditions conducive to bacterial PAH biodegradation were determined. Of six bacterial isolates identified based on their 16S rRNA sequences, Planomicrobium alkanoclasticum could subsist on and consume nearly all hydrocarbons according to the 2,6‐dichlorophenolindophenol assay. The efficacy of this isolate at PAH biodegradation was then empirically confirmed. After 30 days of incubation, P. alkanoclasticum degraded 90.8% of the 16 PAH compounds analyzed and fully degraded eight of them. The optimum P. alkanoclasticum growth conditions were 35°C, pH 7.5, and NaNO3 as the nitrogen source. Under these biostimulant conditions, P. alkanoclasticum degraded 91.4% of the total PAH concentration and completely decomposed seven PAHs after 15 days incubation. Hence, P. alkanoclasticum is an apt candidate for the biodegradation of PAHs and the bioremediation of sites contaminated by them.
