Navedo, Juan G. published the artcileAssessing the effects of human activities on the foraging opportunities of migratory shorebirds in Austral high-latitude bays, Category: isoquinoline, the main research area is .

Human presence at intertidal areas could impact coastal biodiversity, including migratory waterbird species and the ecosystem services they provide. Assessing this impact is therefore essential to develop management measures compatible with migratory processes and associated biodiversity. Here, we assess the effects of human presence on the foraging opportunities of Hudsonian godwits (Limosa haemastica, a trans-hemispheric migratory shorebird) during their non-breeding season on Chiloé Island, southern Chile. We compared bird d. and time spent foraging in two similar bays with contrasting disturbance levels: human presence (mostly seaweed harvesters accompanied by dogs) was on average 0.9±0.4 people per 10 ha in the disturbed bay, whereas it was negligible (95% days absent) in the non-disturbed bay. Although overall abundances were similar between bays, godwit d. was higher in the non-disturbed bay throughout the low tide period. Both days after the start of the non-breeding season and tidal height significantly affected godwit d., with different effects in either bay. Time spent foraging was significantly higher in the non-disturbed bay (86.5±1.1%) than in the disturbed one (81.3±1.4%). As expected, godwit d. significantly decreased with the number of people and accompanying dogs in the disturbed bay. Our results indicate that even a low d. of people and dogs can significantly reduce the foraging opportunities of shorebirds. These constraints, coupled with addnl. flushing costs, may neg. affect godwits’ pre-migratory fattening. Hence, as a first step we suggest limiting human presence within bays on Chiloé to 1 person per 10 ha and banning the presence of accompanying dogs in sensitive conservation areas.

Deus, Lysleine Alves published the artcileHeart rate variability in middle-aged sprint and endurance athletes, COA of Formula: C9H10O3, the main research area is Aging; Athletics; Cardiovascular; Master athletes; Parasympathetic; Running; Sympathetic.

Aging is associated with decreased autonomic balance which could be assessed by Heart Rate Variability (HRV). Exercise training improves autonomic balance, but there is a lack in the literature regarding the heart rate variability (HRV) of master sprinters and endurance athletes. The effects of lifelong endurance and sprint training on cardiac autonomic balance were assessed in master athletes and compared with age-matched controls and young untrained controls. Participants (n = 81) were 8 master sprinters (MS; 51.8 ± 11.1 yrs), 8 master endurance athletes (EN, n = 8, 53.6 ± 8.6 yrs), 17 age-matched untrained (CON, 47.47 ± 6.00 yrs) and 48 young controls (YC, 25.40 ± 3.87 yrs). For the acquisition of RR intervals (iRR) (Polar RS800X Heart Rate Monitor) the participants remained seated for 15-min with the final 10-min being considered for anal. HRV was measured using Kubios software. A one-way ANOVA with repeated measures was applied. All studied parameters did not differ between MS and EN {Time Domain [HR (bpm) 59.00 ± 6.13 vs. 58.94 ± 12.75], [R-R (ms) 1030.45 ± 107.45 vs. 1068.77 ± 206.17], [SDNN (ms) 57.35 ± 20.07 vs. 80.66 ± 71.07], [RMSSD (ms) 40.88 ± 20.07 vs. 38.93 ± 20.44]; Non-linear domain [SD1 (ms) 28.93 ± 14.20 vs. 27.56 ± 14.46]}, whose demonstrated a reduced HR and elevated mean R-R intervals in comparison to both YC {[HR (bpm) 69.64 ± 9.81]; [R-R (ms) 883.93 ± 124.11]} and age-matched controls {[HR (bpm) 70.06 ± 6.63]; [R-R (ms) 865.11 ± 78.39]}. It was observed a lower HRV for middle-aged CON {[RMSSD (ms) 20.23 ± 5.87], [SDNN (ms) 37.79 ± 10.15] and [SD1 (ms) 14.31 ± 4.15]} compared to YC {[RMSSD (ms) 43.33 ± 26.41], [SDNN (ms) 67.07 ± 28.77] and [SD1 (ms) 30.66 ± 18.69; p < .05]}. These last age-related differences were not observed for MS and EN. For master athletes, regardless of whether they are trained in endurance or sprinters, both training modes revealed to be equally beneficial in attenuating the effects of aging on the autonomic balance.

Yepes, Andres F. published the artcileDiscovery of novel donepezil-M30D hybrids with neuroprotective properties for Alzheimers disease treatment, Category: isoquinoline, the main research area is Alzheimers disease mol hybrid neuroprotective pharmacokinetics.

Herein, we designed and synthesized a novel family of mol. hybrids based on the pharmacophoric combination strategy, joining key pharmacophoric features from donepezil and M30D with neuroprotector effects, aiming at obtaining promising medicinal scaffolds for AD treatment. The neuroprotective profile of novel donepezil-M30D hybrids was evaluated by combining the glutamate excitotoxicity assay in neural cells, cytosolic calcium imaging, and through neuron/astrocyte coculture after glutamate exposure. Our results revealed that novel hybrids 6b, 6d, 6g and 6h highlighted for their neuroprotector potency against glutamate-induced excitotoxicity. Specifically, 6d treatment protected cortical neurons treated with an excitotoxic glutamate stimuli recovering calcium dynamics. Likewise, treatment with the 6d hybrid prevented neuronal death and astroglia reactivity in a coculture model of glutamate excitotoxity. Computational simulations and exptl. anal. would suggest that the neuroprotective effects of active compounds could be related to blockade of NMDA channel pore. Optimal pharmacokinetics properties were founded for the most active hybrids involving a remarkable in vitro human plasma stability, as well as suitable in silico ADME profile. In summary, hybridization of key pharmacophoric features from M30D and donepezil provide biol. active compounds that could be used as promising scaffolds for the design of future plasma-stable neuroprotective agents to fight Alzheimers disease (AD).

Ali, Akbar published the artcileExploration of structural, electronic and third order nonlinear optical properties of crystalline chalcone systems: Monoarylidene and unsymmetrical diarylidene cycloalkanones, Application of 2,3-Dimethoxybenzaldehyde, the main research area is structure electronic third order nonlinear optical crystalline chalcone.

In the current study monoarylidene and unsym. diarylidene cycloalkanes, MBMHP, MABP, MBHP, and MBCP have been prepared Their mol. structures were confirmed by SC-XRD. Accompanying the exptl. studies, quantum chem. investigation is performed at the M06/6-311+G(d,p) level, with the natural bond orbital anal. (NBO) performed at the ωB97XD/6-311+G(d,p) level. NBO study showed that the hyper-conjugation and intermol. charge transfer play a remarkable role in stabilizing the crystals and also endorsed the SC-XRD investigations. Furthermore, the band gap of orbitals explained the chem. reactivity and charge transfer phenomena in the above-mentioned crystals. The smallest HOMO/LUMO band gap (4.127 eV) is exhibited by MABP mol. while the highest gap value is found for MBHP to be 4.768 eV.. Global reactivity parameters (GRP) are also explored from the energies of HOMO/LUMO. Among all crystals MBHP has higher value of hardness (η = 2.384 eV) while MABP showed higher global softness (σ = 0.242307 eV). So, from GRP it is revealed that all the studied crystals are less reactive but more stable as suggested by NBO and SC-XRD investigations. NLO study showed that the crystal MBMHP has the higher value of linear polarizability<α> and second hyperpolarizability <γ > 216.36 and 1.06 x 104a.u resp., among all the synthesized crystals. NLO properties of these synthesized crystals may play a significant contribution for the NLO technol. applications.

Zhang, Fang published the artcileComputational discovery, structural optimization and biological evaluation of novel inhibitors targeting transient receptor potential vanilloid type 3 (TRPV3), Quality Control of 86-51-1, the main research area is skin keratinocyte TRPV3 naphthalene amino acid point mutation; Point mutation; Small-molecule inhibitor; TRPV3; Virtual screening.

Transient receptor potential vanilloid type 3 (TRPV3) is a Ca2+ permeable nonselective cation channel and expressed abundantly in skin keratinocytes. TRPV3 emerges as an attractive target for treatment of pruritic, inflammatory, pain and skin-related diseases. However, only a few reports of TRPV3 inhibitors exist at present besides some patents. Therefore, TRPV3 research has always been fraught with challenges. Through a combination of virtual screening and biol. evaluation, compound P1 (10μM) was identified as a top hit with 34.5% inhibitory effect on 2-APB (1 mM)-evoked currents of mTRPV3-WT. Further structural optimization provided the inhibitor PC5 with the best activity (IC50 = 2.63 ± 0.28μM), and point mutation assays indicated that amino acids V629 and F633 are crucial for the binding of PC5 and TRPV3. In summary, these newly discovered inhibitors could serve as promising lead compounds for the development of TRPV3 inhibitors in the future.

Zhang, Qiuyan published the artcileCocktail of Astragalus Membranaceus and Radix Trichosanthis suppresses melanoma tumor growth and cell migration through regulation of Akt-related signaling pathway, Related Products of isoquinoline, the main research area is Astragalus Radix Trichosanthis Akt signaling cell migration growth melanoma; Akt-related singnaling pathway; Astragalus Membranaceus; Radix Trichosanthis; herbal “cocktailâ€? migration; proliferation.

Malignant melanoma has high morbidity and mortality and limited treatment options. Traditional Chinese medicine has great potential in the clin. therapy of cancer, and the theory of compatibility is one core content of Chinese medical theory. Astragalus Membranaceus and Radix Trichosanthis are clin. effective for the treatment of various cancers. We verified the effects of AMD, RTD, and their “”cocktail”” on melanoma model in vitro and in vivo and the mechanism of its effect on the Akt-related signaling pathway by network pharmacol., MTT, flow cytometry, LDH, SOD, MDA assay, and Western blot. The network pharmacol. anal. indicated that the PI3K-Akt pathway plays a crucial role in the treatment of malignant melanoma with these two herbs. In addition, AMD, RTD, and their “”cocktail”” could inhibit the proliferation of A375 cells by reducing the survival rate in a concentration-dependent manner and by regulating the cell cycle, and the compatibility of two herbs also could inhibit melanoma growth. They could, resp., induce apoptosis and inhibit migration by affecting the expression of Bcl-2, Bax, p53, snail, E-cadherin, and N-cadherin. Furthermore, LDH activity was decreased, while SOD increased and MDA reduced. The factors of the Akt-related signaling pathway, Akt and p-Akt, were decreased. This study showed that AMD, RTD, and their “”cocktail”” could regulate cell proliferation, apoptosis, and metastasis in A375 cells through the suppression of the Akt-related signaling pathway, and the “”cocktail”” groups had detoxification and additive effects. The best compatibility of the two herbs also can inhibit tumor growth and metastasis in vivo.
