The aim of controlling/regulating cellular processes by surface patterning of biomaterials is a crucial concept in emerging research fields, where the precise fabrication of micro-nano surface topographies is required at manufacturing scales to meet consumer demand. Photolithography is typically employed for surface patterning; however, the high cost, process complexity, and lack of environmentally friendly and sustainable methodologies represent steep barriers for many researchers. Soft lithographic methods have been utilised extensively as a potential alternative for traditional photolithography, yet a photolithographic step is still required for initial template fabrication. Here, we demonstrate the use of repurposed optical consumer items such as DVDs, diffraction glasses, and gratings that would otherwise be thrown away after their useful lives, being used here as a sustainable approach as templates for the formation of complex nano-patterns. By replicating these templates in polydimethylsiloxane (PDMS) and polylactic acid (PLA), we show the varied interactions of human aortic smooth muscle cells (HAoSMC) to these surfaces. Notably, it was demonstrated that, in comparison to nonpatterned substrates, HAoSMC interaction (adhesion, spreading, and viability) was higher on DVD patterned surfaces compared to diffraction glass and grating patterned surfaces according to the results from cell metabolic activity (MTT and Alamar Blue), and proliferation (total DNA) assays. We demonstrate that a simple, reusable, inexpensive, yet robust technology could be a powerful tool in improving our understanding of cell-surface interactions and for the potential development of medical devices with micro- and nanoscale low or high adhesion features

The study investigated the effects of supplementing the same level of concentrate in different seasons on the growth performance, rumen fermentation, serum biochemical index, and rumen microflora changes in yaks, to provide guidance on accurate feeding of yaks in cold and warm seasons. 12 healthy yaks weighing (124.21±15.64) kg were selected for the experiment, with a warm season group from August to October and a Cold season supplemental feeding group from October to December. The results showed that the mean daily gain was significantly higher in the warm season grazing group than in the cold season grazing group (p<0.05). Rumen fermentation, serum biochemical index, and rumen microflora changes also varied significantly between the two groups (p<0.05).

The present study aimed at the dietary supplementation of zinc oxide nanoparticles on growth, haematological and biochemical parameters of Koi carp. The zinc oxide nanoparticles were synthesized and characterized using UV-VIS, SEM, EDAX, and FTIR. Six feeds were prepared with different quantities of synthesized zinc oxide nanoparticles (F1 - Control, F2 -20 mg, F3 – 40mg, F4 – 60mg, F5-80mg and F6 – 100mg) and feed ingredients are fish meal, groundnut oilcake, wheat flour, and tapioca flour.

Dermatofibroma (DF) is a common benign fibrosing lesion that can be found on any surface of the body, most often in the lower extremities. Dermatofibroma that arises on the digits, as in our present case, may be confused with other clinical entities or even malignant tumors, leading to unnecessarily aggressive treatment. To ensure proper diagnosis and treatment, dermatofibroma should be considered in the differential diagnosis of digital papules.

To contribute to the efficient satisfaction of nutrient needs of guinea pigs, a study on the effect of the inclusion of Ipomea batatas leaves and Stylosanthes guianensis meal on the reproductive performance of guinea pigs was carried out between October 2019 and January 2020 in the Animal Production and Nutrition Research Unit of the University of Dschang. 80 guinea pigs including 64 females and 16 males weighing 448 ± 50 g and aged between 5 and 6 months were identified and distributed randomly into 4 groups of 20 animals each.

Recently, there are unaffordable and dangerous commercial feeds that endanger health and financial aspects of both consumers and producers. Thus, this study was conducted in order to have affordable, quality enhanced and healthy feeds. This investigates the potential of Azolla (Azollapinnata) meal and the reliability of Aguingay (Rotboelliaconchinchinensis) Infloresence meal to have improvement of growth performance and carcass quality supplemented to the Broiler chicken.

Breast cancer ranks first among the most commonly diagnosed cancers in Kenyan females and globally. Treatment is challenging because it is a heterogeneous disease with several subtypes. There has been a significant change in the treatment of Human Epidermal Growth Factor Receptor 2 (HER2) positive breast cancer subtypes following the introduction and widespread use of HER2 targeted therapies.

This research was performed to explore the impacts of guanidinoacetic acid (GAA) supplementation of fish diets with variable energy contents on the growth performance and blood serum parameters of Nile tilapia fish. Nile tilapia Juveniles with an average weight of 20 g were cultured in glass aquaria and fed four formulated pelleted diets for 60 days. Our experiment was divided into four experimental groups: the first group (G1) was fed a basic control diet without any GAA supplementation. The other experimental groups, G2, G3 and G4, were fed diets with different levels of energy (25, 50 and 75 kcal/kg less than in the control, respectively) and supplemented with 0.06% GAA.

The following examinations focus on defining force, its characteristics, and the axiomatic definition of its effect. It is known that the Newtonian axioms define a few characteristics of force and the relationship among force and the parameters (coordinates) of acceleration in the case of movement (acceleration) of point-like bodies.

The study seeks to investigate the casual effect of the efficient energy use and GDP (economic growth) on fossil fuel consumption (Nonrenewable) for the sub Saharan Africa for the period 1980 to 2014. The study also seeks to investigate solutions to environmental issues. Zivot-Andrews unit root test with a structural break, Phillips and Perron unit root test with structural break revealed that the investigated variables become stationary at first-differences. The Gregory-Hansen cointegration test with a structural break shows efficient energy use, economic growth and energy consumption are co-integrated. The long-run estimates obtained from the VECM model indicate that in account of the changes in the structure of the economies, the environmental Kuznets curve does not exist due to validity of a U shaped curve. An increase in output growth (GDP) and efficient energy use positively affect environmental pollution. Based on the findings of this study, the study recommends investment in green technology as the economy growths.

To evaluate the incidence and durability of compensatory hypertrophy with solitary kidneys in the setting of those with multicystic dysplastic kidney or Wilms tumor status post nephrectomy. We conducted a retrospective cohort study of patients with multicystic dysplastic kidney (MCDK) and Wilms tumor (WT). MCDK patients were verified by sonographic findings prenatally. WT patients entered our study at time of nephrectomy. We compared the natural history of hypertrophy between the two cohorts via renal length measurement. We performed linear regression to predict creatinine clearance from renal length after adjusting for age and cohort status (MCDK v. WT).

Spasticity is defined as ‘a disorder of sensorimotor control, resulting from an upper motor neuron (UMN) lesion, presenting as intermittent or sustained involuntary activation of muscles’. It is characterized by increased involuntary velocity-dependent tonic stretch reflexes (muscle tone) with exaggerated tendon jerks, resulting from hyper-excitability of the stretch reflex. In the recent years,a range of non-pharmacological interventions has been used to manage spasticity. Among the novel of all therapies, extracorporeal shock wave therapy (ESWT) is attractive for many researchers since the noninvasive, easy application after well training and afety property. Moreover, the evidences of regeneration of musculoskeletal tissues made ESWT more interesting than other novel therapies.This article will show the evidences, practical clinical use and precaution to guide treating for the clinicians in the novel therapy of ESWT for spasticity. The review of the scientific evidences including methodology components and main results of ESWT treatment on upper limb and lower limb muscles affected by post-stroke spasticity are demonstrated. However, reducing spasticity alone without addressing the negative components of the upper motor neuron syndrome will limit meaningful recovery. A combination of rehabilitation techniques is needed to facilitate functional improvements.
