Examining the Reproductive Rights in the Wake of COVID-19 Pandemic in Nigeria
Authors: Nnawulezi Uche , Adeuti Bosede Remilekun 
Published: February 2021

The prospect of achieving sustainable reproductive rights protection in the wake of the COVID-19 pandemic in Nigeria has remained an intractable problem. To identify and recognize reproductive rights, it is necessary to comprehend that reproductive right embraces certain human rights recognized in national and international laws, including international human rights’ documents. This paper examines the existing Nigeria laws on reproductive and health rights and ascertains the extent to which it has continually and predictably addressed the reproductive rights protection problem. There is a significant protection gap in the national human rights architecture. At the international level, among the poorer adolescent girls between the age of 15-19 years, it frequently results in early pregnancy and, of course, unsafe abortion. Thus, this gap relates in particular to questions on lack of access to family planning services. This paper argues that improvement of reproductive and sexual health goes far beyond the right to life and the right to health of women and girls. To guarantee Nigeria's reproductive rights, a more integral response to these critical human rights and development challenges can address Nigeria's protection gap. This paper adopts an analytical and qualitative approach by referring to existing pieces of literature achieved by the synthesis of ideas. This paper concludes that the adoption of a new approach to policies and programs on preventable maternal mortality and morbidity guarantees the right to attain the highest standard of sexual reproductive health in Nigeria.

A vida urbana vem sofrendo profundas mudanças em decorrência das perdas causadas pela pandemia de Covid 19, que segundo a OMS (Organização Mundial da Saúde) é uma disseminação mundial do novo coronavírus, colocando-nos diante de uma reflexão sobre os desafios para nosso futuro comum: Que modelo de planejamento urbano devemos construir, e como as pessoas poderão se apropriar dos espaços públicos e das áreas verde da cidade de forma segura, inclusiva e com qualidade de vida nesse período durante e após pandemia? A pandemia declarada em 11/03/2020 pela OMS colocou em questão e ressaltou a importância das áreas verdes e dos espaços públicos urbanos, em contrapartida ao isolamento social a que todos ficamos submetidos, como a única “vacina” disponível para evitarmos a contaminação. Ao mesmo tempo, esse futuro incerto, nos remete a perguntas e incertezas sobre a maneira como enfrentar a crise climática, e fortalecer a sustentabilidade urbana e a qualidade de vida das pessoas em todo o planeta. A retrospectiva das pandemias que o mundo vem enfrentando, enfatiza a importância das áreas verdes na qualidade ambiental urbana das cidades, tendo como um dos principais elementos de preocupação a saúde das pessoas. Nesse sentido, será necessário propor mudanças no espaço físico e na forma de uso dos espaços públicos e das áreas verdes como forma de ressignificação da vida urbana.

Banjarmasin is dominated with the combination of land and river, which resulted many riverside areas in the city. These areas are functioned as settlements area, as well as commercial and public areas as the focus of the city’s development and the local’s daily activities. However, the rapid development in Banjarmasin still giving less attention to the development of green open spaces, despite the local connection with the river. Therefore, this research aimed to identify the local perception of green open space in the riverside areas of Banjarmasin through descriptive qualitative analysis. Questionnaires and observations in five study areas were done to obtain the local perception. The results show that the highest local perception index is for the social aspects for 87,2 points and the lowest local perception index is the spatial planning aspects for 42,6 points. Banjarmasin needs to focus more on the spatial planning of green open spaces in riverside areas and enhancing the opportunity for locals to participate in any spatial planning process (participatory planning).

Dorsal Medial Cuneiform Bony Outgrowth—Apophysis or Exostosis
Authors: Malige Ajith , Surrey Lea F. , Davidson Richard 
Published: February 2021

Case:
Three female children (11-15 years) presented with painful dorsomedial medial cuneiform masses that did not improve after conservative treatment. Findings were consistent with a diagnosis of medial cuneiform apophysis. After surgical resection, no patients had recurrence, although one continued to have pain from a deep peroneal nerve sensory branch that was resected. One patient had an intramass physis identified.

Conclusion:
When surgically removing dorsomedial cuneiform masses, surgeons should decompress overlying sensory nerve branches, detach and subsequently repair muscular attachments, and remove the entire stump to prevent regrowth because some of these masses may be apophyses and not exostoses.

Published: February 2021

Case:
A Division I collegiate softball catcher presented with discoloration, coolness, and swelling of her left index finger that worsened with sport participation. Upper extremity arteriogram revealed absent flow to the radial aspect of the finger and compromise of the ulnar digital artery distal to the proximal interphalangeal joint. After failing nonoperative management, she underwent periarterial sympathectomy with relief of symptoms.

Conclusion:
Repetitive trauma to a catcher's hand can result in vascular compromise. When nonoperative measures fail, surgical intervention may be successful. We describe successful treatment using sympathectomy. Surgeons should be able to diagnose this condition and understand treatment options.

Published: February 2021

Abstract
Rivers finding their path through different hamlets, industries and residential etc. are the end receivers of liquid and solid waste. This plight of water bodies has been deteriorating the life of the river stretches and greatly impacting the quality of water. The identification of potentially polluted locations and timely action can help in restoring the water quality of the river stretches and improving the life of water body as well. The dynamics of river Ganga stretches has been modeled using Non-linear Autoregressive network with exogenous inputs (NARX) model spatially and temporally simultaneously. This method helps in developing one single model to understand all the stretches simultaneously which is not possible otherwise. The change in behavior of NARX model under consecutive and non-consecutive time period has also been studied using statistical methods and multi-step ahead predictions. The model developed in this study captures all the seasons together in one single model and has been used to predict BOD values at seven different locations for nine months ahead. The results highlight the performance ability of NARX model to understand future water quality changes of river Ganga stretch owing to continuous pollution adding to the river. The results predicted for 9 months ahead for year 2015 using two different models, a lower root mean square error (RMSE) as 0.026 and higher correlation coefficient ‘r’ as 0.992 was obtained for model with consecutive days while for other model with non-consecutive days the RMSE was 0.031 and r was 0.989. This information may provide some guidance to the policy makers and water managers to prepare and suggest the pollution mitigation measures for the life line of millions; River Ganga.
Performance analysis of Tunnel FET based Ring Oscillator using Sentaurus TCAD
Authors: Yadav Menka 
Published: February 2021

Abstract
A detailed Sentaurus TCAD simulation based study for Silicon Double Gate Tunnel Field Effect Transistor (Si-DG TFET) based Ring Oscillator (RO) is presented in this work. Two different ring oscillator topologies (simple RO and Negative Skewed Delay RO )are presented with two different structures for TFET device. The two structures are different in the source-drain extension regions widths. The extension region width variation effects are studied and presented for inverter and ring oscillator. A TFET based inverter is presented to show the changes in behavior due to variations in the drain extension region widths, which is later used for RO designs. The drain extension region width changes the drain extension region resistances which in turn is responsible for change in the corresponding device properties. RO simulation are used for calculating the delay. To further explore digital and analog applications transfer characteristics and noise margins of inverter are explored with power supplies variations. Better reliability for oscillation frequency is obtained using Negative Skewed Delay ring oscillator (NSD RO) topology. NSD RO is resulting in lesser jitter, more reliable frequency as compared to single-ended ring oscillator topology. By tuning the supply voltage of the device the ring oscillator frequency can be used for RF applications, thus it works like a voltage controlled oscillator (VCO).

Abstract
Background: Thyroid cancer (TC) has inflicted huge threats to the health of mankind. Chlorophenols (CPs) were persistent organic pollutant and can lead to adverse effects in human health, especially in thyroid. However, epidemiological studies have revealed a rare and inconsistent relationship between internal exposure to CPs and TC risk. This study was designed to examine the association between urinary CPs and risk of TC in Chinese population.Methods: From June 2017 to September 2019, a total of 297 histologically confirmed TC cases were recruited. Age and gender matched controls were enrolled at the same time. Gas chromatography-mass spectrometry (GC-MS) was used to determine the levels of three CPs in urine. Conditional logistic regression models were adopted to assess the potential association. Restricted cubic spline function was used to explore the non-liner association.Results: After adjusting for confounding factors, multivariate analysis showed that, compared with the first quartile, the fourth quartile concentrations of 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP) and pentachlorophenol(PCP) were associated with TC risk [odds ratio (OR)2,4-DCP =2.28, 95%confidence interval (CI): 1.24-4.18; OR2,4,6-TCP =3.09, 95% CI: 1.66-5.77; ORPCP =3.30, 95% CI: 1.71-6.36, respectively]. When CPs were included in the multivariate model and restricted cubic spline function as continuous variables, presenting significant dose-response relationships. Meanwhile, whether in the TC group with tumor diameter > 1 cm or metastatic TC, the changes of 2,4,6 TCP and PCP concentrations were positively correlated with the risk of TC. Conclusions: Our study suggests that higher concentrations of urinary CPs are associated with increased TC risks. Moreover, 2,4,6-TCP and PCP have certain effects on the invasiveness of thyroid cancer. Targeted public health policies should be formulated to reduce the CPs pollution. These findings need further in-depth studies to confirm and relevant mechanism also needed to be clarified.

Published: February 2021

Abstract
Background: This study aimed to investigate the biological functions of exosome in follicle microenvironment and illustrate the underlying mechanism about the different IVF outcomes among normal, diminished ovarian reserve (DOR) and aging female patients with the same biological ovarian age. Methods: Follicular fluid (FF) was collected from control(n=35), DOR(n=35), aging(n=35) who underwent IVF therapy in 2017 and 2018. Electron microscope and NanoSight were used to detect the exosomes morphology and concentration. Hormones levels and anti-Müllerian hormone (AMH) in the serum were detected by ELISA. Results: Serum FSH and FSH level of the DOR group and the aging group significantly increased, AFC was decreased compared to the control. Exosomes concentrations were significantly lower in DOR and aging as compared with control group and were also significantly lower in the aging group compared with the DOR group. Exosomes was negatively correlated with FSH and FSH/LH, exosomes was positively correlated with AMH. GDF9 and BMP15 were secreted by exosomes. Conclusions: Exosome was highly represented in human FF and are involved in maturation of follicle. The concentration of exosomes in FF can be an indicator of ovarian reserve. Oocytes may secrete exosomes.
