Microplastics could be ingested by many organisms, including zooplankton, involving bioaccumulation and biomagnification mechanisms a cross food webs. The information about microplastic ingestion by zooplankton keeps increasing worldwide. However, it is still limited for particle sizes under 300 μm (small microplastics, SMPs) and in areas such as Southeast Asia, which is considered one of the hotspots for plastic debris.

This study assessed the organic matter (OM) digestion efficiency on plankton samples and the MPs' weight, size, and polymer changes under different digestion techniques. For this, 2-step (KOH and HO + Fe) and 3-step (2-step and enzymes) digestion techniques were assessed under different duration and temperature conditions.

The lack of established disease models has hampered therapy development. We generated a panel of cancer tissue-originated spheroid (CTOS) lines derived from SCNEC of the uterine cervix using a method based upon cell-cell contact throughout the preparation and culturing processes.

Neuroendocrine carcinoma of small cell type (SCNEC) is a rare pathological subtype in cervical cancer, which has a worse prognosis than other histological cell types. Due to its low incidence and the lack of experimental platforms, the molecular characteristics of SCNEC in the cervix remain largely unknown. Using the cancer tissue-originated spheroid (CTOS) method-an ex vivo 3D culture system that preserves the differentiation status of the original tumors-we established a panel of CTOS lines of SCNEC.

We retrospectively reviewed cases of 84 pregnant JW patients and 95 deliveries from April 2001 to August 2017. We examined the acceptance rates of blood transfusions, blood products, and autotransfusion types in patients who experienced postpartum hemorrhage (PPH), and investigated estimated hemorrhage volume at delivery and PPH treatments.

Methods: Patients who developed recurrent or persistent cervical cancer in a previously irradiated field and were subsequently treated with salvage surgery (the surgery group) or palliative care alone (the palliative group) were identified. Patient characteristics, treatment-related complications, and survival were retrospectively compared between the two groups.
Hardly any report exists on the influence of hysteroscopic myomectomy on subsequent pregnancy. Placenta accreta is most often associated with placenta previa in women with multiple prior cesarean sections. We report the first case of placenta accreta without placenta previa during the first pregnancy subsequent to hysteroscopic myomectomy.

Therefore, we present a case report of cervical varix complicating placenta previa before describing our findings in the context of an electronic database search of relevant reports. In the case report, we describe the clinical course and imaging results of a 35-year-old woman who was diagnosed with cervical varix complicated by placenta previa.

In revising compensation for medical treatment, shifts in home care systems such as management of lifestyle-related diseases, management of a patient within reach of a daily medical treatment, and an attempt to curtail hospitalization are suggested as concrete means of planning medical expenses to be appropriate. In doing this, it is getting more important that the medical institution pursue its purpose and must select the course of treatment and to solidify a medical cooperation among the institutions because a medical treatment is often not concluded at only one medical institution. Although a revision of compensation for medical treatment is getting more difficult due to three consecutive negative revisions in the past, a new clinical path for a local solidarity of femoral neck fracture has been found.
