The sole inhibitory Fcγ receptor CD32b (FcγRIIb) is expressed throughout B and plasma cell development and on their malignant counterparts. CD32b expression on malignant B cells is known to provide a mechanism of resistance to rituximab that can be ameliorated with a CD32b-blocking antibody. CD32b, therefore, represents an attractive tumor antigen for targeting with a monoclonal antibody (mAb). To this end, two anti-CD32b mAbs, NVS32b1 and NVS32b2, were developed. Their complementarity-determining regions (CDR) bind the CD32b Fc binding domain with high specificity and affinity while the Fc region is afucosylated to enhance activation of FcγRIIIa on immune effector cells. The NVS32b mAbs selectively target CD32b+ malignant cells and healthy B cells but not myeloid cells. They mediate potent killing of opsonized CD32b+ cells via antibody-dependent cellular cytotoxicity and phagocytosis (ADCC and ADCP) as well as complement-dependent cytotoxicity (CDC). In addition, NVS32b CDRs block the CD32b Fc-binding domain, thereby minimizing CD32b-mediated resistance to therapeutic mAbs including rituximab, obinutuzumab, and daratumumab. NVS32b mAbs demonstrate robust antitumor activity against CD32b+ xenografts in vivo and immunomodulatory activity including recruitment of macrophages to the tumor and enhancement of dendritic cell maturation in response to immune complexes. Finally, the activity of NVS32b mAbs on CD32b+ primary malignant B and plasma cells was confirmed using samples from patients with B-cell chronic lymphocytic leukemia (CLL) and multiple myeloma. The findings indicate the promising potential of NVS32b mAbs as a single agent or in combination with other mAb therapeutics for patients with CD32b+ malignant cells.Kinesins constitute a superfamily of ATP-driven microtubule motor enzymes that convert the chemical energy of ATP hydrolysis into mechanical work along microtubule tracks. Kinesins are found in all eukaryotic organisms and are essential to all eukaryotic cells, involved in diverse cellular functions such as microtubule dynamics and morphogenesis, chromosome segregation, spindle formation and elongation and transport of organelles. In this review, we explore recently reported functions of kinesins in eukaryotes and compare their specific cargoes in both plant and animal kingdoms to understand the possible roles of uncharacterized motors in a kingdom based on their reported functions in other kingdoms.

Traditionally, physical movement has been limited for cardiac surgery patients, up to 12-weeks post-operatively. Patients are asked to use "standard sternal precautions," restricting their arm movement, and thereby limiting stress on the healing sternum.

To compare return to function, pain/discomfort, wound healing, use of pain medication and antibiotics, and post-operative length of hospital stay in cardiac surgery patients having median sternotomy who used standard sternal precautions or Keep Your Move in the Tube movement protocols post-operatively.

A quasi-experimental design was used (100 standard sternal precautions and 100 Keep Your Move in the Tube patients). Patients were followed in person or by telephone over a period of 12-weeks postoperatively. Outcomes were measured at day 7, as well as weeks 4, 8, and 12 weeks.

The majority of participants (77% in each group) were male and had coronary artery bypass graft surgery (66% standard sternal precautions and 72% Keep Your Move in the Tube). Univariate analysis revealed the standard sternal precautions group had lesser ability to return to functional activities than the Keep Your Move in the Tube group (

<0.0001) over time. This difference was minimized however, by week 12. Multivariate analysis revealed that increasing age, body mass index, and female sex were associated with greater functional impairment over time, but no difference between standard sternal precautions and Keep Your Move in the Tube groups.

Keep Your Move in the Tube, a novel patient-oriented movement protocol, has potential for cardiac surgery patients to be more confident and comfortable in their recovery.

The present review summarizes the evidence regarding the relationship between diet and IPF in humans, and in animal models of pulmonary fibrosis, in which we discuss the bioactivity of specific dietary food ingredients, including fatty acids, peptides, amino acids, carbohydrates, vitamins, minerals and phytochemicals. Interestingly, many animal studies reveal preventive and therapeutic effects of particular compounds. Furthermore, it has been recently suggested that the lung and gut microbiota could be involved in IPF, a relationship which may be linked to changes in immunological and inflammatory factors. Thus, all the evidence so far puts forward the idea that the gut-lung axis could be modulated by dietary factors, which in turn have an influence on IPF development. Overall, the data reviewed here support the notion of identifying food ingredients with potential benefits in IPF, with the ultimate aim of designing nutritional approaches as an adjuvant therapeutic strategy.Our aim in this study was to investigate whether the behaviors of dairy cows on pasture, predicted with accelerometer data and combined with GPS data, can be used to better understand the relationship between behaviors and pasture characteristics. During spring 2018, 26 Holstein cows were equipped with a 3D-accelerometer and a GPS sensor fixed on a neck-collar for five days. The cows grazed alternatively in permanent and in temporary grasslands. The structural elements, soil moisture, slope and botanical characteristics were identified. Behaviors were predicted every 10 s from the accelerometer data and combined with the GPS data. The time-budgets expressed in each characterized zone of 8 m × 8 m were calculated. The relation between the time-budgets and pasture characteristics was explored with a linear mixed model. In the permanent grassland, dairy cows spent more time under a tree to ruminate (p less then 0.001) and to rest (p less then 0.001) and more time to graze in areas with Holcus lanatus (p less then 0.
