Comparison of Publications on Heated Tobacco Products With Conventional Cigarettes and Implied Desirability of the Products According to Tobacco Industry Affiliation: A Systematic Review.

Introduction: Heated tobacco products (HTPs) have been advertised as "reduced-harm" tobacco products compared to conventional cigarettes (CC); however, no direct evidence supporting HTPs being desirable for human health exists. A previous systematic review reported that evidence on HTPs published in 2017 or earlier was primarily drawn from industry-related papers. We aimed to investigate whether tobacco industry-affiliated studies are more likely to conclude that HTPs are more desirable than CC.

Comparison of Residual Dimethyl Sulfoxide (DMSO) and Ethylene Glycol (EG) Concentration in Bovine Ovarian Tissue During Warming Steps Between Slow Freezing and Vitrification.

Background: DMSO and EG have been used as cryoprotectants for human ovarian tissue cryopreservation, but residual cryoprotectants concentration and safety have rarely been reported.

Objective: We aimed to compare residual cryoprotectants (DMSO, EG) concentration in bovine ovarian tissue during warming steps between one kind of common slow freezing method and two kinds of vitrification methods, which are usually used for cryopreservation of human ovarian tissue in Japan.

Materials And Methods: In this study, we used five bovine ovaries with an average age of 24.

Cu MS (M=V, Nb, Ta) and its Solid Solutions with Sulvanite Structure for Photocatalytic and Photoelectrochemical H Evolution under Visible-Light Irradiation.

Solid solutions with of Cu VS with either Cu NbS or Cu TaS (Cu Nb V S or Cu Ta V S ) were prepared by a solid-state reaction and adopted a sulvanite structure. Their band gaps were 1.6-1.

Long-term clinical outcomes of testicular sperm extraction and intracytoplasmic sperm injection for infertile men.

Purpose: To find the best methods to achieve the highest pregnancy and birth rates for couples needing testicular sperm extraction (TESE)-intracytoplasmic sperm injection (ICSI).

Methods: Retrospectively studied were 801 patients with male factor infertility who had undergone TESE-ICSI between April, 1996 and July, 2016 and who had been categorized into four groups: obstructive azoospermia (OA); non-obstructive azoospermia (NOA); Klinefelter syndrome (KS); and cryptozoospermia (Crypt). The sperm retrieval rate, hormone levels, fertilization rate (FR), pregnancy rate (PR), and birth rate (BR) after ICSI among three groups were compared: fresh testicular sperm (FS)-fresh oocytes (FO) (Group I); frozen-thawed testicular sperm-FO (Group II); and FS-vitrified-warmed oocytes (Group III).

Efficacy of the endometrial receptivity array for repeated implantation failure in Japan: A retrospective, two-centers study.

Aim: This study aimed to assess the efficacy of the endometrial receptivity array (ERA) as a diagnostic tool and the impact of personalized embryo transfer (pET) for the treatment of patients with recurrent implantation failure (RIF) in Japan.

Methods: Fifty patients with a history of RIF with frozen-thawed blastocyst transfers were recruited from July, 2015 to April, 2016. Endometrial sampling for the ERA and histological dating and a pET according to the ERA were performed.
