Recently the GexOy nanomaterials have been studying intensively due to their interesting electronic materials, which have many particular properties and applications in nanotechnology and nano-devices fabrication. Much work has been done on many different synthesis methods and their properties of Ge and GexOy nanomaterials. However, the effects of the different Ge substrate surface states and Au catalyst layer thicknesses on the formation of different forms/morphologies of nanomaterials (nanowires, nanorods, nanopa [...]

Laser acupuncture, a rising complementary therapy, applies a low-intensity laser to acupuncture points, yet its underlying mechanisms remain unclear. Proposed hypotheses include modulation of cellular signaling, tissue repair, and immune modulation. Laser acupuncture may stimulate energy flow, neurotransmitter release, cellular changes, immune regulation, and neuroendocrine activity. Additionally, the biophoton theory suggests an involvement of ultra-weak photon radiation from cells. Litscher et al. explore these m [...]

Objective: Reversal learning requires an individual to alter their behavior when previously learned reward-based contingencies are reversed. Reversal learning is heavily influenced by cognitive flexibility, which has been shown to be enhanced with acute exercise. However, minimal work has directly evaluated the effects of acute exercise on reversal learning, which was the purpose of this experiment. Methods: A between-subject randomized controlled intervention was employed. Participants (N=60) were randomized into [...]

Schools play an integral role in providing opportunities for children of all ages to be exposed to nutrition education. There are a variety of ways children can receive nutrition education in the school setting, such as explicit lessons, modeled dialogue, and exposure to nutrition-based principles. However, there continues to be a disconnect between teacher perceptions of nutrition education and time spent implementing it in the classroom. Nutrition education can come in many forms, including hands-on gardening and [...]

3D printed PLA has already been demonstrated for several biotechnological applications, including enzymes immobilization. The prerequisites for an efficient screening assay include using small volumes of reagents, low cost, and rapid screening of large numbers of compounds and extracts. Hence, assays based on microtiter plates are predominant. Thus, designing and fabricating scaffolds on a similar scale, which could serve as immobilization carriers, and their recruitment in inhibitors screening studies is of great [...]

Background: Cardiac allograft vasculopathy (CAV) remains a major obstacle to long-term heart allograft survival. A number of studies show that immune mechanisms are involved in CAV. Using non-invasive cellular MRI (CMRI) to explore indicators of CAV lesions and characterize its development could provide new insights into the target immune cells that are responsible for the progression of CAV and reveal early markers of the disease before irreversible changes occur. Methods and Results: Rat heart transplant allograf [...]

This article explores a strategy to empower vulnerable communities by transferring solar technology as a path to energy justice development. The proposed methodology is based on preliminary research on energy uses according to the needs, practices, and customs of the communities. The study focuses on the cases of three women with productive vocations based on entrepreneurship in different phases of incubation found in a peri-urban community in central Mexico. In this community, productive energy uses include a) the [...]

In orthopedics and oncology, benign and malignant bone lesions pose significant clinical challenges. Malignant tumors, like osteosarcomas and multiple myeloma, pose substantial health dangers and can spread common and mostly non-life-threatening benign lesions, including non-sizing fibromas and unicameral bone cysts. Treatment plans for bone lesions may involve radiation, chemotherapy, and surgical excision, depending on their type. Combining stem cell research, bioactive materials, and advanced scaffold design, cu [...]

The experiment was carried out at the laboratories of the National Commission for Biotechnology in Syria during the period 2020-2022 to detect the somaclonal genetic variation occurring in callus cultures at different ages and to compare them with the In vitro growing plants and introduced species of Rose Periwinkle that grew up in the Syrian environment, in addition, exploring the effect of abiotic stresses in causing genetic variations in callus, by the Inter Simple Sequence Repeats technique (ISSR) using 21 prim [...]

We fabricated three thermo-rechargeable batteries using low-cost transition metal hexacyanoferrate and determined the thermal voltage (Vcell) and discharge capacity (Qcell) per unit weight of the total active material in the cathode and anode. The obtained values were compared with the calculated values, which were determined by analyzing the temperature and capacity coefficients of the redox potential.
