Here we describe a culture technique of cells dissociated from the external muscularis of the guinea pig small intestine, which allows us to maintain all the elements involved in the intestinal peristaltic reflex. After a few days in culture, these cells reorganize to form a small group of cells that permit the generation of pacemaker activity, spontaneous contractions, and the development of inhibitory and excitatory junction potentials in the petri dish, all elements involved in the peristaltic reflex. Therefore, these co-cultures are suitable to study the cellular and molecular aspects related to the development, maintenance, and modulation of motor intestinal functions.

Biomimetic hydrogels have garnered increased interest due to their considerable potential for use in various fields, such as tissue engineering, 3D cell cultivation, and drug delivery. The primary challenge for applying hydrogels in tissue engineering is accurately evaluating their mechanical characteristics. In this context, we propose a method using scanning ion conductance microscopy (SICM) to determine the rigidity of living human breast cancer cells MCF-7 cells grown on a soft, self-assembled Fmoc-FF peptide hydrogel.

-produced blastocysts are exposed to different stimuli when compared with ones. This includes the culture of embryos in a sturdy petri-dish, while embryos develop in a soft and dynamic structure. Here we hypothesized that a softer environment could differently modulate the produced embryos To that aim, presumptive zygotes were produced by fertilization and divided into three groups: 1) Cultured in a regular Petri dish - Control (CON); 2) Cultured on top of an alginate hydrogel surface (TOP); 3) Encapsulated inside an alginate hydrogel sphere (ENC) and cultured.

Background: Early chick mortality (ECM) is one of the most important problems of the poultry industry that causes severe economic losses to the farmers. The chick mortality varies in different geographical locations and its etiological factor also varies.
Aim: The aim of the present work was to isolate and identify various etiological agents responsible for causing ECM in broilers, and study the overall occurrence and pathology of various disease conditions responsible for causing ECM in broilers.

Ground covers areused inproduce production to enhance plant growth and control diseases and pests. While various factors are considered when selecting commercial ground covers, food safety, particularly the survival of foodborne pathogens, is often overlooked. This study aimed to assess the survival ofSalmonellaon different ground covers, including biodegradable mulch, landscape fabric, and plastic mulch.

Phytophthora blight caused by Phytophthora capsici is a serious disease affecting a wide range of plants. Biochar as a soil amendment could partially replace peat moss and has the potential to suppress plant diseases, but its effects on controlling phytophthora blight of container-grown peppers have less been explored, especially in combination of biological control using Trichoderma. In vitro (petri dish) and in vivo (greenhouse) studies were conducted to test sugarcane bagasse biochar (SBB) and mixed hardwood biochar (HB) controlling effects on pepper phytophthora blight disease with and without Trichoderma.
