Circulating tumor DNA (ctDNA) has been widely used as a minimally invasive biomarker in clinical routine. However, a number of factors such as panel design, sample quality, patients' disease stages are known to influence ctDNA detection sensitivity. In this study, we systematically evaluated common factors associated with the variability of ctDNA detection in plasma and investigated ctDNA abundance in bronchoalveolar lavage (BAL).

Despite such ambitions, realized emissions reductions continue to fall alarmingly short of modeled energy transition pathways for achieving net-zero. This gap is largely a result of the difficulty of realistically modeling all the techno-economic and sociopolitical capabilities that are required to deliver actual emissions reductions.

The main compounds in ginger rhizome can be classified as gingerols, diarylheptanoids, and volatile oils. The composition and concentrations of the bioactive compounds in ginger rhizome might vary according to the age of the rhizome.

Methods: By analyzing patients' demands, outpatient service system and emergency system complemented each other with the help of "internet medical" to provide online medical treatment, self-diagnosed pneumonia program, online pharmacies, outpatient appointment and online pre-examination services, open green channels for special patients, and to provide referral services for critical patients. The COVID-19 suspected patients and other common fever patients were separated from other patients.
Phonon-polaritons (PhPs) in layered crystals, including hexagonal boron nitride (hBN), have been investigated by combined scattering-type scanning near-field optical microscopy (s-SNOM) and Fourier transform infrared (FTIR) spectroscopy. Nevertheless, many of such s-SNOM-based FTIR spectra features remain unexplored, especially those originated from the impact of boundaries. Here we observe real-space PhP propagations in thin-layer hBN sheets either supported or suspended by s-SNOM imaging.

Objective: To explore the effectiveness of the zygomatic spindle-shaped osteotomy and internal push of titanium screw anchor for prominent malar.
Methods: Between July 2011 and January 2015, 58 patients with prominent malar underwent zygomatic spindle-shaped osteotomy and internal push of titanium screw anchor. There were 3 males and 55 females, aged 18-33 years (mean, 23 years).

Objective: To determine the effect of AQP1 gene on facial nerve edema following injury through investigation of the relationship between the expression of AQP1 gene and Schwann cells swelling.
Methods: The AQP1 expression in Schwann cells of mouse facial nerve tissues was detected by immunofluorescent staining. The transgenic protocol by lentivirus transduction was used to specifically upregulate AQP1 expression in Schwann cells.

Objective: To investigate the treatment of auricular keloid with dinuclear surgery and intralesional injection of compound Betamethasone.
Methods: From Jan. 2008 to Jan.
Scattering-type scanning near-field optical microscopy (s-SNOM) provides few nanometer optical spatial resolution and is compatible with nearly any form of linear and nonlinear optical spectroscopy. We have developed a versatile s-SNOM instrument operating under cryogenic and variable temperature (∼20-500 K) and compatible with high magnetic fields (up to 7 T). The instrument features independent tip and sample scanning and free-space light delivery with an integrated off-axis parabolic mirror for tip-illumination and signal collection with a numerical aperture of N.

Objective: To investigate the effect of topical application of leptin in promoting burn wound healing in rats.
Methods: Four parallel second-degree burn wounds induced on the back of 18 Wistar rats were divided into leptin treatment group (treated with topical application of 400 ng/ml leptin dissolved in PBS) and control group (treated with PBS). The time of wound healing was recorded, and the wound area that was not healed was measured at 3, 7, 11, 15, and 19 days after burns.

Objective: To investigate the clinical directive significance of three-dimensional reconstruction of CT in treating mandibular angle hypertrophy.
Methods: Between March 2009 and January 2011, 18 patients with mandibular angle hypertrophy were treated using the three-dimensional reconstruction technology of CT. All patients were female, aged 20-36 years with an average of 25 years.

Growth hormone (GH) plays important roles in oocyte development and facilitates the successful production of competent oocytes in many species both in vivo and in vitro. However, the mechanism of GH action on oocyte maturation is not well known. In this paper, the temporospatial messenger ribonucleic acid expression patterns of GH and several other GH-related factors were quantitatively analyzed in porcine cumulus-oocytes complex throughout in vitro maturation (IVM).

The full-length mouse Foxp4 cDNA encodes a 685-amino-acid protein that is similar to Foxp1 and Foxp2. Foxp4 gene expression is observed primarily in pulmonary, neural, and gut tissues during embryonic development.

To define the role that GATA6 plays during lung epithelial cell development, we expressed a GATA6-Engrailed dominant-negative fusion protein in the distal lung epithelium of transgenic mice. Transgenic embryos lacked detectable alveolar epithelial type 1 cells in the distal airway epithelium.
