The estimated NPP showed negative values in summer, which indicated that respiratory carbon loss exceeded photosynthetic carbon gain. In contrast, NPP was positive in the spring and winter seasons throughout the 10 years. Autumn NPP varied widely, showing both positive and negative values. The annual NPP also showed considerable year-to-year variations. Additionally, we examined the effects of temperature conditions on NPP assuming annual temperature changes of 0 °C (present temperature), + 1 °C, and + 2 °C. The results indicated that NPP decreased with increasing temperature, except in the winter season. The findings of this study suggest that climate warming has a large impact on the NPP of R. japonicum; however, the impact can be both positive and negative depending on the season. The results also suggest that future climate warming is likely to decrease NPP on an annual basis.

Seed dispersal allows plants to colonize new habitats that has an significant influence on plant distribution and population dynamics. Orchids produce numerous tiny seeds without endosperm, which are considered to be mainly wind-dispersed. Here, we report avian seed dispersal for an early diverging orchid species, Neuwiedia singapureana, which produces fleshy fruits with hard seed coats in the understory of tropical forests.

Neuwiedia singapureana produced fleshy fruits that turned red in autumn, and birds were confirmed to be the primary seed dispersers. As compared to its sister species, N. veratrifolia with dehiscent capsular fruits, embryos of N. singapureana were larger and enclosed by thickened and lignified seed coats. After passing through the digestive tracts of birds, the seeds still stayed alive, and the walls of seed coat contained several cracks. The germination percentage increased significantly for digested seeds as compared with seeds from intact fruits.

The thickened and lignified seed coat may protect seeds as they passed through the digestive tracts of birds. Taken together with a recent report of insect-mediated seed dispersal system in the subfamily Apostasioideae, the animal-mediated seed dispersal may be an adaptive mechanism promoting the success of colonization in dark understory habitats.

Progestin-primed ovarian stimulation (PPOS) is a new ovarian stimulation protocol that has been used over the last decade to enhance reproductive function. The purpose of this study is to evaluate whether PPOS is as effective as conventional protocols (without GnRHa downregulation).

Search terms included "medroxyprogesterone", "dydrogesterone", "progestin-primed ovarian stimulation", "PPOS", "oocyte retrieval", "in vitro fertilization", "IVF", "ICSI", "ART", and "reproductive". The selection criteria were nonrandomized studies and randomized controlled studies. For data collection and analysis, the Review Manager software, Newcastle-Ottowa Quality Assessment Scale and GRADE approach were used.

The clinical pregnancy rates were not significantly different in either RCTs or NRCTs [RR 0.96, 95% CI (0.69-1.33), I

 = 71%, P = 0.81]; [RR 0.99, 95% CI (0.83-1.17), I

 = 38%, P = 0.88]. The live birth rates of RCTs and NRCTs did not differ [RCT RR 1.08, 95% CI (0.74, 1.57), I

 = 66%, P = 0.69; NRCT OR 1.03 95% CI 0.84-1.26), I

 = 50%, P = 0.79]. The PPOS protocol had a lower rate of OHSS [RR 0.52, 95% CI (0.36-0.75), I

 = 0%, P = 0.0006]. The secondary results showed that compared to the control protocol, the endometrium was thicker [95% CI (0.00-0.78), I

 = 0%, P = 0.05], the number of obtained embryos was higher [95% CI (0.04-0.65), I

 = 17%, P = 0.03] and more hMG was needed [in NRCT 95% CI (307.44, 572.73), I

 = 0%, P < 0.00001] with the PPOS protocol.

The PPOS protocol produces more obtained embryos and a thicker endometrium than the control protocol, with a lower rate of OHSS and an equal live birth rate. The PPOS protocol could be a safe option as a personalized protocol for infertile patients.

To investigate whether CD73 had a role in the pathogenesis of polypoid endometriosis.

Our study included 15 cases of polypoid endometriosis, which were diagnosed between 2005 and 2019. Clinical findings were gathered from archive files of relevant clinics and pathology reports. All glass slides were re-examined for confirmation of the diagnosis and the detection of additional microscopic findings. An immunohistochemical examination was performed using anti CD73 antibodies in 15 cases of polypoid endometriosis, and also in a control group that contained 9 cases of endometrial polyps and 9 cases of ovarian conventional endometriosis.

In addition to standard gynecologic operations, major non-gynecologic procedures had to be performed in 7 cases. In two cases, the surgical team comprised only general surgeons, and a misdiagnosis of carcinoma was made during the frozen section in one case. The majority of the cases displayed gross polypoid lesions that measured 0.7-13cm. The most common sites were the ovary adenosine balance, may contribute to the pathogenesis of this rare form of endometriosis.

In December 2019, the emerging of a novel coronavirus (COVID-19) has influenced the whole world. The current pandemic also triggers several psychological changes. Uncertainties and changes in health practices may cause anxiety, depression, and concerns on vulnerable populations such as pregnant. This study aims to survey the pregnant women to capture the psychological impact and perceptions during the pandemic.

A total of 297 pregnant women aged ≥ 18years were enrolled in May 2020. We evaluated the hard-copy survey included questions about demographic and clinical information of patients, 95% confidence intervals of a COVID-19-related questionnaire in a Likert scale and 14-item Hospital Anxiety and Depression Scale (HADS).

A total of 297 pregnant women were included in this study with a mean age of 27.64. Most patients (82.5%) had concerns about infecting their babies during delivery. The fear of infection of the fetus during delivery revealed elderly age and having anxiety as the unique significant risk factors.
