g and efficacy. In this review, we present a historical perspective of Parkinson's Disease pathogenesis, detection, and conventional therapy, animal and human models investigating the gut-origin hypothesis, in vitro models to enable controlled discovery, and future outlooks for this blossoming field.

Chest trauma causes substantial morbidity and mortality and its severity is assessed using clinical diagnosis or scoring systems like Injury severity score (ISS) and thoracic trauma severity score (TTSS). Association of inflammatory cytokines with severity of disease and final clinical outcome is not clearly defined in patients with chest trauma. In this study, we thought to evaluate the inflammatory response in serum and bronchoalveolar lavage fluid (BALF) in chest trauma patients and correlate the level of extracellular cytokines with diseases severity and final outcome.

A total of 65 patients with blunt chest trauma and 30 healthy controls were enrolled in this prospective observational study. Assessment of inflammatory cytokines such as Interleukin (s) - IL-5, IL-13, IL-2, IL-6, IL-9, IL-1β, IFN-γ, TNF-α, IL-17A, IL-17F,IL-4, IL-21 and IL-22 was performed in both serum and bronchoalveolar lavage fluid using 13-plex multiplex kit using fluorescence-encoded bead based immunoassays.

A significantly higher level of IL-13, IL-2, IL-6, IL-9, IL-1β, IFN-γ, TNF-α, IL-17A, IL-17F, IL-21 and IL-22 cytokines were observed in patients with blunt chest trauma compared to healthy controls. Level of IL-2, IL-6, IL-1β and IL-17A was significantly raised in the patients with blunt chest trauma who had a fatal outcome during the hospital stay. An elevated cytokine response of IL-13, IL-4, and IL-21 was noted in the group of patients with high (>5) thoracic trauma severity score.

Routine monitoring of the inflammatory cytokine level in patients with chest trauma may be used routinely. Longer prospective studies should be encouraged to determine the role of cytokines in patients with chest trauma in predicting the patient final clinical outcome.

Here, we report that Arabidopsis thaliana CHLOROPHYLLASE 1 (CLH1) plays important roles in the PSII repair process. The abundance of CLH1 and CLH2 peaks in young leaves and is induced by high-light exposure. Seedlings of clh1 single and clh1-1/2-2 double mutants display increased photoinhibition after long-term high-light exposure, whereas seedlings overexpressing CLH1 have enhanced light tolerance compared with the wild type. CLH1 is localized in the developing chloroplasts of young leaves and associates with the PSII-dismantling complexes RCC1 and RC47, with a preference for the latter upon exposure to high light. see more Furthermore, degradation of damaged D1 protein is retarded in young clh1-1/2-2 leaves after 18-h high-light exposure but is rescued by the addition of recombinant CLH1 in vitro. Moreover, overexpression of CLH1 in a variegated mutant (var2-2) that lacks thylakoid protease FtsH2, with which CLH1 interacts, suppresses the variegation and restores D1 degradation. A var2-2 clh1-1/2-2 triple mutant shows more severe variegation and seedling death. Taken together, these results establish CLH1 as a long-sought chlorophyll dephytylation enzyme that is involved in PSII repair and functions in long-term adaptation of young leaves to high-light exposure by facilitating FtsH-mediated D1 degradation.Neural synchrony in the brain is often present in an intermittent fashion, i.e., there are intervals of synchronized activity interspersed with intervals of desynchronized activity. A series of experimental studies showed that this kind of temporal patterning of neural synchronization may be very specific and may be correlated with behaviour (even if the average synchrony strength is not changed). Prior studies showed that a network with many short desynchronized intervals may be functionally different from a network with few long desynchronized intervals as it may be more sensitive to synchronizing input signals. In this study, we investigated the effect of channel noise on the temporal patterns of neural synchronization. We employed a small network of conductance-based model neurons that were mutually connected via excitatory synapses. The resulting dynamics of the network was studied using the same time-series analysis methods as used in prior experimental and computational studies. While it is well known that synchrony strength generally degrades with noise, we found that noise also affects the temporal patterning of synchrony. Noise, at a sufficient intensity (yet too weak to substantially affect synchrony strength), promotes dynamics with predominantly short (although potentially very numerous) desynchronizations. Thus, channel noise may be one of the mechanisms contributing to the short desynchronization dynamics observed in multiple experimental studies.Gold nanoparticles (AuNPs) have been widely used as nanocarriers in drug delivery to improve the efficiency of chemotherapy treatment and enhance early disease detection. The advantages of AuNPs include their excellent biocompatibility, easy modification and functionalization, facile synthesis, low toxicity, and controllable particle size. This study aimed to synthesize a conjugated citraconic anhydride link between morphologically homogeneous AuNPs and doxorubicin (DOX) (DOX-AuNP). The carrier was radiolabeled for tumor diagnosis using positron emission tomography (PET). The systemically designed DOX-AuNP was cleaved at the citraconic anhydride linker site under the mild acidic conditions of a cancer cell, thereby releasing DOX. Subsequently, the AuNPs aggregated via electrostatic attraction. HeLa cancer cells exhibited a high uptake of the radiolabeled DOX-AuNP. Moreover, PET tumor images were obtained using radiolabeled DOX-AuNP in cancer xenograft mouse models. Therefore, DOX-AuNP is expected to provide a valuable insight into the use of radioligands to detect tumors using PET.
