This study aimed to systematically analyze the efficacy of therapeutic exercise on activities of daily living (ADL) and cognitive function among older residents in long-term care facilities.PubMed, Cochrane Central of Register Trials, Physiotherapy Evidence Database, OTseeker, and Ichushi-Web were searched from inception until December 2018.Databases were searched to identify randomized controlled trials (RCTs) of therapeutic exercise for long-term care facility residents aged 60 years and older, focusing on ADL and cognitive function as outcomes.Two independent reviewers extracted the key information from each eligible study. Two reviewers independently screened and assessed all studies for eligibility, extracting information on study participants, details of interventions, outcome characteristics, and significant outcomes. Any discrepancies were resolved by a third reviewer.A total of 11 RCTs with 1,280 participants were eligible for analyses. Therapeutic exercise had a significant benefit on ADL (standard mean difference [SMD] = 0. 22, 95% confidence interval [CI]: 0.02, 0.42, p = 0.03)]. Subgroup analyses indicated that interventions were conducted ≥ 3 days per week [SMD = 0.42, 95% CI 0.02, 0.82, p = 0.04]. For cognitive function, group exercise and ≥ 3 days/week of intervention had a significant benefit (group exercise: mean difference [MD] = 3.36, 95% CI 0.91, 5.80, p = 0.007; ≥ 3 days/week of intervention: MD = 2.28, 95% CI 0.07, 4.49, p = 0.04).Therapeutic exercise conducted 3 or more days per week may be effective for improving ADL and cognitive function among older residents in long-term care facilities. This meta-analysis suggested that group exercise for cognitive functions was effective. However, the effective method of intervention delivery for ADL was unclear.

The purpose of this systematic review and meta-analysis was to investigate the effects of low-intensity resistance training on knee extension strength with respect to intensity, frequency, duration and training site in community-dwelling older adults.A literature search was conducted for articles published up to December 2018 on PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Physiotherapy Evidence Database (PEDro), OTseeker and Ichushi-Web. Randomized controlled trials involving resistance training with60 % one repetition maximum (1RM) in community-dwelling older adults aged 60 years and older were eligible.In total, 7 studies involving 275 participants were included in the meta-analysis. The results showed significant improvements in knee extension strength with low-intensity resistance training [standardized mean difference (SMD) 0.62, 95 % confidence interval (CI) 0.32 to 0.91]. In subgroup analyses, significant improvements were observed in the group with intensity at 50-60 % 1RM (0.83, 0.46 to 1.19), but not in the group at 40 % or less 1RM (0.30, 95%CI: -0.08 to 0.68). Concerning frequency, there were significant improvements in knee strength for those receiving training three times (0.90, 0.52 to 1.27) and two times (0.36, 0.03 to 0.69) per week, with a significant difference between the groups (p = 0.04).Low-intensity resistance training should be considered as an effective intervention to improve knee extension strength in community-dwelling older adults. Older adults may show more improvement in knee extension strength if intensity of the training is set at 50-60 % 1RM and frequency of training is three times per week.

A total synthesis of 6,7-dihydroeponemycin 2 was achieved via the epoxide intermediate 8a . Unresolved absolute configuration of the epoxide ring in 2 and eponemycin 1 was determined to be 2 R by application of the asymmetric Sharpless epoxidation of 9 .

Controlled crisscross annulation was applied to the synthesis of (±)-dihydrodesoxyotonecine, a degradation product of secopyrrolizidine alkaloids.

The synthesis of the nuclei of pyrrolizidine and indolizidine could be readily achieved by use of the one pot reaction named as “crisscross annulation”, which was extended to the synthesis of (±)-heliotridane ( 16 ) and (±)-nuphar indolizidine ( 20 ), a minor component of dried scent glands of the Canadian beaver.

Phoracantholide I, having a ten-membered lactone, was synthesized through a new synthetic method which includes a cyclic acetylenic oxy-Cope rearrangement and ring-expansion by the Baeyer-Villiger oxidation of a nine-membered ketone.

A synthesis of 9a-hydroxy-5,8-dideoxomitosanes was accomplished by the transannular cyclization of hydro-1-benzazocinone intermediates derived from 3-(2,5-dioxo-1-methylcyclopentyl)-6-methyl-p-phenylenediamine derivatives. These mitosanes were led to the 8-membered ring system by an oxidative ring-opening reaction.

(±)-Tryptoquivaline G was formally synthesized through shortened steps from tryptophan, in which oxidation with thallium(III) trinitrate(TTN) was effected at the crucial stage. The present work also constitutes the first synthesis of oxindole lactones carrying 2-alkyl quinazolinones.
