Cell walls are vital to the normal growth and development of plants as they protect the protoplast and provide rigidity to the stem. Here, two poplar and Arabidopsis orthologous endoglucanases, which have been proposed to play a role in secondary cell wall development, were examined. The class B endoglucanases, Pt GH9B5 and At GH9B5, are secreted enzymes that have a predicted glycosylphosphatidylinositol anchor, while the class C endoglucanases, Pt GH9C2 and At GH9C2, are also predicted to be secreted but instead contain a carbohydrate-binding *** poplar endoglucanases were expressed in Arabidopsis using both a 35 S promoter and the Arabidopsis secondary cell wall-specific Ces A8 promoter. Additionally, Arabidopsis t-DNA insertion lines and an RNAiconstruct was created to downregulate At GH9C2 in Arabidopsis. All of the plant lines were examined for changes in cell morphology and patterning, growth and development, cell wall crystallinity, micro fibril angle, and proportion of cell wall carbohydrates. Misregulation of Pt GH9B5/At GH9B5 resulted in changes in xylose content, while misregulation of Pt GH9C2/At GH9C2 resulted in changes in crystallinity, which was inversely correlated with changes in plant height and rosette diameter. Together, these results suggest that these endoglucanases affect secondary cell wall development by contributing to the cell wall crystallization process.

I mmunosuppressive therapies have meaningful effects on the treatment of multiple sclerosis(MS),a classical inflammatory autoimmune disease of the central nervous system.1 In mice with experimental autoimmune encephalomyelitis(EAE),a murine model of human MS,we showed that an adoptive transfer of GM-CSF and Interleukin-15 Fusion Transgene(GIFT15)-derived regulatory B cells(GIFT15 Bregs)sustained a durable remission of the disease.2,3 These regulatory B cells require the expression of MHC class II and IL-10 for suppressive activity.

The study proposes to explore two alternative medicine therapies--qigong and yoga for balanc- ing the essential duo of holistic mind-body and consequently offer a solution for stress, uncertainty, anxiety and depression. Qualitative research methods have been used to create a conceptual synthesis of yoga and qigong. It is suggested that an increased sense of control is the interface between these two modalitieso This conceptual congruence of qigong and yoga is thought to be a selective, curative method, a prescription for ideal living and a ground of human essence existence. Furthermore, this essence is thought to enhance the mind＇s self-regulatory processes and prevent mental health disorders. The two alternative therapies can prevent mental health disorders such as anxiety, depression and, minimize mental health disruptions such as stress and poor quality of life. It is suggested that patients and/or clients can benefit from this fusion.

The nutritional value of kudzu (Pueraria lobata) was evaluated as a potential animal feed. Randomly selected samples from natural habitats with Jacksonville area (Alabama, USA) were utilized in the study. Kudzu leaves showed significantly higher dry matter and crude protein content than the stems;whereas, ADF fiber was significantly lower in the leaves. However, NDF and total digestible nutrients (TDN) were similar in the leaves and the stems. The leaf part of kudzu was especially rich in CP (24.46%) and met the requirements and recommendations for most ruminants. The TDN value for kudzu stem is 55.99%, which falls below but within the recommended range. Macronutrients concentration between the stem and leaf of kudzu, nitrogen, calcium, and magnesium showed a significantly higher in the leaf than the stem. However, phosphorous was similar in concentration in the stem and the leaf, and potassium was higher in the stem. In regard to the micronutrients, the only significant difference between the leaf and the stem was iron. However, iron, manganese, zinc, and copper were all above the recommended concentrations by the National Research Council. In general, kudzu can be considered a good source for animal feed, especially the leaf, which shows a higher value in most of the determined criteria in comparison to what was recommended by the National Research Council. This should provide a new outlook to kudzu, which has been considered a noxious weed and help in the utilization of kudzu in a positive way in the southern region of the US.
