The "Huang gua" melons were measured for their physical properties including firmness and static elastic modulus. The vibrational characteristics of fruits and vegetables are governed by their elastic modulus (firmness), mass, and geometry. Therefore, it is possible to evaluate firmness of fruits and vegetables based on their vibrational characteristics. Analysis of the vibration responses of a fruit is suggested for measuring elastic properties (Firmness) non-destructively. The impulse response method is often used to measure firmness of fruits. The fruit was excited using three types of balls (wooden, steel and rubber) and the vibration is detected by an accelerometer. The Instron device was used to measure the static elastic modulus of the inner, middle and outer portions of melon flesh. Finite element (FE) technique was used to determine the optimum excitation location of the chosen measurement sensor and to analyze the mode shape fruits. Four types of mode shapes (torsional or flexural mode shape, first-type, second-type spherical mode and breathing mode shape) were found. Finite element simulation results agreed well with experimental results. Correlation between the firmness and resonant frequency (r2=0.91) and between the resonant frequency and stiffness factor (r2=0.74) existed. The optimum location and suitable direction for excitation and response measurement on the fruit were suggested.

To explore the automated immunostainer screening anaplastic lymphoma kinase (ALK) gene fusion non-small cell lung cancer (NSCLC) and clinicopathological characteristics of the molecular subtype lung cancers. Methods Five hundred and sixty-six cases of NSCLC were collected over a 16 month period. The test for ALK was performed by Ventana automated immunostainer with anti-ALK D5F3. The histological features, treatment and outcome of patients were assessed. Results Thirty-eight cases (6.7%, 38/566) of NSCLC showed ALK gene fusion. The frequency of ALK gene fusion was higher in male (7.1%, 25/350) than that in female (6.0%, 13/216) patients, but not achieving statistical significance (chi2 = 0.270, P = 0.604). ALK + NSCLC was more significantly more frequent in patients < or = 60 years (9.9%, 28/282) than >60 years (3.5% , 10/284) of age. Histologically, the ALK + NSCLCs were mostly adenocarcinoma (81.6%, 31/38) , among which eighteen cases were solid predominant subtype with mucin production; nine cases were acinar predominant subtype; one case was papillary predominant subtype and three cases were invasive mucinous adenocarcinoma. The ALK + non-adenocarcinoma included three cases of squamous cell carcinoma, three cases of adenosquamous carcinoma and one case of pleomorphic carcinoma. Among the ALK + NSCLC patients, the number of non/light cigarette smokers (86. 8% , 33/38) was more than that of heavy smokers. Twenty-nine cases were stages III and IV; twenty-nine cases showed lymph node metastasis; twenty cases showed metastases mostly to brain and bone; and one case showed EGFR gene mutation coexisting with ALK gene fusion. Twelve of fifteen patients received crizotinib therapy and remained stable. Conclusions NSCLC with ALK gene rearrangement shows distinctive clinical and histological features. Ventana-IHC may he a feasible and valid technique for detection of ALK rearrangement in NSCLC.

Objective:
To evaluate the clinicopathologic characteristics of lung non-terminal respiratory unit (non-TRU) type adenocarcinoma.
Methods:
Seventy-two cases of lung non-TRU type adenocarcinoma that underwent complete resection and diagnosed at Departments of Pathology, Affiliated Suzhou Hospital of Nanjing Medical University and Nanjing General Hospital of the PLA from January 2005 to December 2016 were retrospectively studied. The histomorphological changes and precursor lesions were observed under microscope. The expression of lineage-specific markers and tumor stem cell markers was detected by immunohistochemistry (IHC). The major driver mutations of lung adenocarcinoma were tested by ARMS and directive gene sequencing.
Results:
Non-TRU type adenocarcinomas were more commonly found in male (65.3%, 47/72), former or current smokers (68.1%, 49/72), the elder (mean 61 years old), central adenocarcinoma (75.0%, 54/72), tumors with necrosis (61.1%, 44/72) and higher grade (73.6%, 53/72). Histologically, non-TRU type adenocarcinoma displayed complex histomorphology and was often composed of large irregular gland-like and acinar pattern accumulating extracellular mucin, necrotic tumor cell debris and neutrophils, or invasive adenocarcinoma with mucin production. The tumor cells were composed of bronchial surface epithelial cells, mucinous column cells, polygonal cells and goblet cells. Eighteen (25.0%), 23 (31.9%) and 28 (38.9%) cases exhibited ciliated columnar cell metaplasia (CCCM), mucous columnar cell change (MCCC) and bronchiolar columnar cell dysplasia (BCCD) (precursor lesion of lung adenocarcinoma). IHC showed the expression of CK7 (100.0%, 72/72), TTF1 (12.5%, 9/72), Napsin A (5.6%, 4/72), MUC5AC (81.9%, 59/72), MUC5B (87.5%, 63/72), p53 (66.7%, 48/72), CK5/6 (12.5%, 9/72), p63 (18.1%, 13/72), CK20 (19.4%, 14/72) and CDX2 (16.7%, 12/72) in the tumor cells. The expression of tumor stem cell markers was detected in 43.1% cases (31/72) for CD44, 31.9% (23/72) for CD133, 58.3% (42/72) for β-catenin, 36.1% (26/72) for ALDH1, 12.5% (9/72) for GATA6, 20.8% (15/72) for SOX2 and 29.2% (21/72) for OCT4. The driver mutations were 26.4% (19/72) for KRAS, 2.8% (2/72) for EGFR and 1.4% (1/72) for EML4-ALK, and none for BRAF and ROS1.
Conclusion
Non-TRU type adenocarcinoma is an uncommon subtype of lung adenocarcinoma with distinct clinicopathologic characteristics, histologic appearances, immunophenotype and molecular genetic alterations.

Coronary artery disease (CAD) is a complex human disease, involving multiple genes and their nonlinear interactions, which often act in a modular fashion. Genome-wide single nucleotide polymorphism (SNP) profiling provides an effective technique to unravel these underlying genetic interplays or their functional involvements for CAD. This study aimed to identify the susceptible pathways and modules for CAD based on SNP omics. First, the Wellcome Trust Case Control Consortium (WTCCC) SNP datasets of CAD and control samples were used to assess the joint effect of multiple genetic variants at the pathway level, using logistic kernel machine regression model. Then, an expanded genetic network was constructed by integrating statistical gene–gene interactions involved in these susceptible pathways with their protein–protein interaction (PPI) knowledge. Finally, risk functional modules were identified by decomposition of the network. Of 276 KEGG pathways analyzed, 6 pathways were found to have a significant effect on CAD. Other than glycerolipid metabolism, glycosaminoglycan biosynthesis, and cardiac muscle contraction pathways, three pathways related to other diseases were also revealed, including Alzheimer’s disease, non-alcoholic fatty liver disease, and Huntington’s disease. A genetic epistatic network of 95 genes was further constructed using the abovementioned integrative approach. Of 10 functional modules derived from the network, 6 have been annotated to phospholipase C activity and cell adhesion molecule binding, which also have known functional involvement in Alzheimer’s disease. These findings indicate an overlap of the underlying molecular mechanisms between CAD and Alzheimer’s disease, thus providing new insights into the molecular basis for CAD and its molecular relationships with other diseases.

Cyclodextrin can increase the solubility of poorly soluble drugs, but also decrease the permeability of poorly soluble drugs in inclusion complexes simultaneously, which partially or completely counteracts the contribution of improvement in solubility to the oral absorption of poorly soluble drugs. If a competing agent is added to the system to compete binding sites of cyclodextrins with drugs, drug permeability can be improved by increasing the concentration of free drugs in the inclusion complex system. In this paper, a rapid

BCS Ⅱ drugs are characterized by low solubility and high permeability. Improving their solubility is considered an important approach to improve its oral absorption. Recent strategies to increase the solubility of poorly-soluble drugs may unexpectedly result in greatly depressed permeability, ultimately leading to failure in improving oral absorption. Based on the mathematics of membrane permeability coefficient of a drug, the membrane/aqueous partition coefficient is dependent on the drug's solubility in the gastrointestinal milieu, suggesting a unique interplay between the solubility and permeability of the drug, and treating the one irrespectively of the other may be insufficient. When we focus on the increase of drug solubility and overlook the efficacy of drug permeability, the positive effect of increased solubility to drug oral absorption might be traded off by depressed permeability. To provide rational formulary designs, by optimizing excipients and evaluation, this review summarizes solubility- permeability interplay for different types of solubilizing techniques, such as cyclodextrin, surfactants-based vehicle, cosolvent, amorphous solid dispersions, other infectors such as P-gp transporters and new techniques for simultaneous evaluation of drug solubility and permeability.
