The enhanced ability to detect accurate location and measure the depth of a   metal inside a biological tissue is very useful in the assessment of medical condition and treatment. This manuscript proposed a solution via the measurement of the tissue properties using magnetic induction spectroscopy (MIS) method to describe the characterization of biological soft tissue. The objective of this study is to explore the viability of locating embedded metal inside a biological tissue by measuring the differences the biological tissue electrical properties using principle of Magnetic Induction Spectroscopy (MIS). Simulation is done using COMSOL Multiphysics software for accurate information on the involved parameters for both metal and biological tissues. Simulation has confirmed that MIS capable of detecting and locate embedded metal inside a biological tissue.

Camellia yuhsienensis Hu, a species of tea oil tree with resistance to anthracnose, is widely used to breed disease-resistant Camellia varieties. In 2019, anthracnose symptoms were observed on Ca. yuhsienensis for the first time. However, the species and biological characteristics of Colletotrichum spp. isolated from Ca. yuhsienensis (YX-Colletotrichum spp.) have not been elucidated. In this study, five isolates (YX2-5-2, 2YX-3-1, 2YX-5-1, 2YX-8-1-1 and 2YX-8-1-2), which were consistent with the morphological characteristics of Colletotrichum spp., were obtained from Ca. yuhsienensis. A phylogenetic analysis demonstrated that YX2-5-2, 2YX-3-1 and 2YX-8-1-2 belonged to first clade along with Colletotrichum fructicola. 2YX-8-1-1 belonged to the second clade along with Colletotrichum siamense. 2YX-5-1 belonged to the third clade with Colletotrichum camelliae. Pathogenicity tests revealed that the pathogenicity of YX-Colletotrichum spp. was stronger than that of Colletotrichum spp. isolated from Camellia oleifera (GD-Colletotrichum spp.). Biological characteristics illustrated that the mycelial growth of YX-Co. camelliae (2YX-5-1) was slower than that of GD-Co. camelliae when the temperature exceeded 20 °C. In addition, in the presence of ions, the mycelial growth of YX-Co. fructicola (YX2-5-2) and YX-Co. siamense (2YX-8-1-1) was also slower than that of GD-Co. fructicola and GD-Co. siamense. Furthermore, the ability of YX-Colletotrichum spp. to utilize lactose and mannitol was weaker than that of GD-Colletotrichum spp., while the ability to utilize NH4+ was generally stronger than that of GD-Colletotrichum spp. This is the first report of anthracnose of Ca. yuhsienensis induced by Co. fructicola, Co. siamense and Co. camelliae in China. These results will provide theoretical guidance for the study of the pathogenesis and control of anthracnose on Ca. yuhsienensis.

Six potato virus Y isolates from Victoria and Queensland were characterized on the basis of host plant reactions. Four isolates from potato produced symptoms in indicator plants and potato cultivars consistent with those caused by the PVYO group. Two isolates from tobacco produced necrotic symptoms on some tobacco cultivars characteristic of the PVYN group, but did not systemically infect potato cultivars and therefore could not be considered to belong to any of the previously described PVY strain groups. Despite the wide variation in their biological characteristics, an antiserum produced to one of the potato isolates was able to detect all six of the isolates when used in ELISA

In this paper it is shown the design, simulation and characterization of Moly Permalloy based electromagnetic sensor in MEMS software. The dimension of the device is minimized to the smallest the software can simulate which is 1 micron. Total of 9 models had been simulated which differs in thickness of the material and designs. A new design was created to compare the results with the existing designs. The creation of the new design has given better results than the existing designs in terms of the current flow and the magnetic induction.

A chondrocyte progenitor population isolated from the surface zone of articular cartilage has become a promising cell source for cell-based cartilage repair. The cartilage-derived stem/progenitor cells are multipotent stem cells, which can differentiate into three cell types in vitro including adipocytes, osteoblasts, and chondrocytes. Much work has been done on cartilage stem/progenitor cells (CSPCs) from people, horses, and cattle, but the relatively little literature has been published about these cells in chickens. In our work, CSPCs were isolated from chicken embryos in incubated eggs for 20 days. In order to inquire into the biological characteristics of chicken CSPCs, immunofluorescence, reverse transcription-polymerase chain reaction (RT-PCR), and flow cytometry were adopted to detect the characteristic surface markers of CSPCs. Primary CSPCs were subcultured to passage 22 and, for purpose of knowing the change of cell numbers, we drew the growth curves. Isolated CSPCs were induced to adipocytes, osteoblasts, and chondrocytes. Our results suggest that we have identified and characterised a novel cartilage progenitor population resident in chicken articular cartilage and CSPCs isolated from chickens possess similar biological characteristics to those from other species, which will greatly benefit future cell-based cartilage repair therapies.

The use of an electrolytic respirometer for characterization of chemical compounds and wastewater was studied. From the BOD curves generated by the respirometer, the first order biokinetic constant (K), ultimate BOD (BODu) and adaptation period were estimated. The estimated ultimate BOD values of the known chemical compounds were very close to the theoretical oxygen demand values. Using K values, the relative biodegradability of the chemicals could be compared while the adaptation period for each compound could vary with the type of seed micro-organisms used. It was found that BOD5 values determined by the conventional method have no or very little, if any, meaning as far as the biological characteristics of industrial wastewaters are concerned. The BOD curves for wastewaters consisting of 2 or 3 different compounds could be divided into several stages while those for the combined wastewaters could be expressed as one curve.
