Background: Lung cancer is the leading cause of cancer morbidity and mortality. Its management has a significant economic impact on society. Despite a high incidence of cancer, so far, there is no national register for this disease in Morocco. The main goal of this report was to estimate the medical costs of lung cancer in our country. Methods: We first estimated the number of annual new cases according to stage of the disease on the basis of the Grand-Casablanca-Region Cancer Registry data. For each sub-group, the protocol of treatment was described taking into account the international guidelines, and an evaluation of individual costs during the first year following diagnosis was made. Extrapolation of the results to the whole country was used to calculate the total annual cost of treatments for lung cancer in Morocco. Results: Overall approximately 3,500 new cases of lung cancer occur each year in the country. Stages I and II account for only 4% of cases, while 96% are diagnosed at locally advanced or metastatic stages III and IV. The total medical cost of lung cancer in Morocco is estimated to be around USD 12 million. This cost represents approximately 1% of the global budget of the Health Department. According to AROME Guidelines, about 86% of the newly diagnosed lung cancer cases needed palliative treatment while 14% required curative intent therapy. The total cost of early and advanced stages lung cancer management during the first year were estimated to be 4,600 and 3,420 USD, respectively. Conclusion: This study provides health decision-makers with a first estimate of costs and the opportunity to achieve the optimal use of available data to estimate the needs of health facilities in Morocco. A substantial proportion of the burden of lung cancer could be prevented through the application of existing cancer control knowledge and by implementing tobacco control programs.
Kudzu vine(Pueraria montana var. lobata) is an invasive climbing woody vine that envelops trees and shrubs, pressing physically and shutting out sunlight, which needs to be controlled. Kudzu vine pathogens were surveyed as a way to seek its biocontrol agents in 2002. Occurrence of a bacterial halo blight disease of kudzu vine was observed at several localities in Korea including Euiwang and Suwon in Gyeonggi Province, Daejon, and Gochang and Buan in Jeonbuk Province. Symptoms of brown to black spots with a surrounding yellowish halo appeared from June and lasted till the rainy season without much expansion, but accompanying often leaf blight and defoliation. Isolated bacteria were identified as Pseudomonas syringae pv. phaseolicola based on physiological and cultural characteristics, Biolog, fatty acid and 16S rDNA sequencing analyses. In artificial inoculation test, these bacteria produced the same halo spot symptoms on kudzu vine and bean plants. They also induced hypersensitive responses (HR) on tobacco, tomato, and chili pepper leaves. This is the first report of a bacterial disease of kudzu vine in Korea, and the bacterial pathogen can be used as a biocontrol agent against the pest plant.

Background: Oral cancer stands among the 10 top causes of cancer death in the world. Considering the role of epidemiologic information on planning and effective interventions, the present study aimed to investigate the epidemiology of oral cancer in Iran. Materials and Methods: The required information for this systematic review study was obtained from PubMed, Google Scholar, CINAHL,SID, Medlib, Magiran and Iranmedex databases, using key words "cancer", "oral cancer", "squamous cell carcinoma", "oral cavity carcinoma" and their Persian equivalents in combination with keywords of epidemiology, prevalence, etiology, frequency, and Iran from 1990 to 2014. From 1,065 related studies found, finally 25 were included to the study. Results: The mean age of 8,248 patients in 25 studies was $54.0{\pm}15.1years$. The male/female ratio for oral cancer was 1.91. Tongue with average percentage of 29.9 was the most involved site. Regarding microscopic grade, 65.7% of cases were grade 1. SCCs, accounting for an average of 70.0%, was the most common among all types of oral cancer. In the majority of studies, smoking including cigarette, hookah, and tobacco consumption was found to be a risk factor. Conclusions: The epidemiological pattern of oral cancer in Iran is somewhat similar to that of other countries. Yet the information on hand in this field is limited and considering the role of epidemiological data we suggest conducting more accurate studies to catch data that is required for effective programs and interventions.
Background: The burden due to cancers is an emerging public health concern especially in resource-limited countries like Nigeria. The WHO estimates that cancer kills more people than tuberculosis, HIV/AIDS and malaria combined. As people in Nigeria and other developing countries are beginning to survive infectious diseases, there is an observed epidemiologic transition to chronic diseases, such as cancers. In 2008, 75 out of 1,000 Nigerians died of cancer. Despite the rising incidence and public health importance, Nigeria lacks an organized and comprehensive strategy to deal with cancers. Materials and Methods: This article reviewed 30 peer-reviewed manuscripts on cancer care in four countries. It highlights the limitations to cancer care in Nigeria; due to lack of awareness, low health literacy, absence of organized screening programs, inadequate manpower (in terms of quality and quantity) as well as limited treatment options. Results: This review led to the formulation of a proposal for Nigerian National Cancer Policy, mainly drawn from effective strategies used in Canada, Brazil and Kenya. This is a vertical cancer program that is patient-centered with an emphasis on tobacco control and cancer disease screening (similar to Canada and Brazil). Additionally, it emphasizes primary cancer prevention (similar to Kenya). Its horizontal integration with other disease programs like HIV/AIDS will improve affordability in a poor resourced country like Nigeria. Capacity building for health professionals, hub-and-spoke implementation of screening services, as well as investment in effective treatment options and increased research in cancer care are essential. International 'twinning collaborations' between institutions in richer countries and Nigeria will enhance effective knowledge translation and improve the quality of patient care. Conclusions: A national cancer policy must be developed and implemented in Nigeria in order to overcome the present limitations which help contribute to the observed increases in cancer morbidity and mortality rates. Cancer control is feasible in Nigeria if the nation was to consider and employ some of the cost-effective strategies proposed here.

Seed coating by a phenazine-producing bacterium, Pseudomonas chlororaphis O6, induced dose-dependent inhibition of germination in wheat and barley seeds, but did not inhibit germination of rice or cucumber seeds. In wheat seedlings grown from inoculated seeds, phenazine production levels near the seed were higher than in the roots. Deletion of the gacS gene reduced transcription from the genes required for phenazine synthesis, the regulatory phzI gene and the biosynthetic phzA gene. The inhibition of seed germination and the induction of systemic disease resistance against a bacterial soft-rot pathogen, Erwinia carotovora subsp. carotovora, were impaired in the gacS and phzA mutants of P chlororaphis O6. Culture filtrates of the gacS and phzA mutants of P. chlororaphis O6 did not inhibit seed germination of wheat, whereas that of the wild-type was inhibitory. Our results showed that the production of phenazines by P. chlororaphis O6 was correlated with reduced germination of barley and wheat seeds, and the level of systemic resistance in tobacco against E. carotovora.
A fungal infection assay between normal and transgenic potato harboring chitinase gene in cultivar Belchip was investigated. In the first stage of experiment, seven transgenic lines having 12cm tall were tested for their resistance against potato late blight pathogen Phytophthora infestans by infection with the zoospores, artificially, Susceptibility to potato late blight infection could be classified into three types based on the rate. In terms of resistance to the disease, two lines were higher, two lines were more suppressive, and three lines were similar as compared with the control. In the following experiment, only 2 risistant lines and 1 suppressed line were used to confirm the resistance again. The results of both experiments were similar. Furthermore, two highly resistant transgenic lines grown in field exhibited a higher resistance than control under the conditions of natural ocurrence of the fungal disease.
From June 1979 to July 1988 for 9 years, total 440 cases of lung cancer[including biopsy and surgical specimen] of the Pusan Paik hospital were examined for the clinical and pathology study. The findings of the study are as follows; [1] The incidence of lung cancer started to increase from 1982, and it again remarkably increased since 1987. Such increase was solely brought by the increase of male lung cancer. Male and female ratio is 5.6: 1. [2] Histopathologically, the most prevalent type is squamous cell carcinoma[60.ado], and next are adenocarcinoma[15.6%] and small cell carcinoma[15.0%]. But in female alone, the most prevalent type is adenocarcinoma[40.3%], and next are squamous cell carcinoma[37.3%] and small cell carcinoma[11.9%]. [3] The absolute number of adenocarcinoma are approximately equally distributed among both sexes until 60 years of age. Above 61 years of age, mostly male was shown while female was not. Most probably, many female patient.- of that old age simply did not visit general hospitals for surgery in Korea. [4] Surgical treatment was performed in 8% of total cases of lung cancer. And most cases showed stage I progression of the cancer. Average size of the cancer was 5 cm in diameter in the operated 35 cases suggesting that the cancer could be detected more than 10 years ago before the time of surgery. [5] Lung cancer affected more in the right lung [right: left=1.6: 1], and each upper lobe of both lungs are affected about 1/4 of cases indicating that about 1/2 of all lung cancer develop from the upper lobes. [6] There are more nonsmokers[67.6%] among the lung cancer patients[male 64.6%, female 82.1%]. Probably, this will mean that there are other potent carcinogenic agents in our environment like automobile exhaust beside tobacco smoke. For the past history of lung disease other than cancer, tuberculosis is the most prevalent disease[16.1%, male 17.4%, female 9.0%]. Most of them is probably not related etiologically though this possibility is not completely denied.

Objectives: The aim of this study was to investigate the effectiveness of a hospital-based smoking cessation intervention for increasing continuous abstinence rate from smoking in patients with cerebral infarction. Methods: One-hundred and two smokers with cerebral infarction who decided to quit smoking were enrolled in the smoking cessation intervention from December 2012 to February 2015. The smokers underwent six consecutive times of individual intervention with nurse specialist on smoking cessation including education on behavioral modification, counseling for withdrawal symptoms, and anti-smoking advice over a 12-month period. Results: Among the total participants, the continuous abstinence rate from smoking changed from 79.4% at 1 month to 60.8% at 12 months after discharge. The continuous abstinence rate from smoking after 12 months was 88.5% in participants who completed the entire program (6 times), while 51.3% in participants who did not complete the entire program (${\leq}5$ times) (P=0.001). After adjustment for general and smoking-related characteristics, complete implementation of hospital-based smoking cessation intervention was significantly associated with continuous abstinence from smoking after 12 months (odds ratio: 5.93; 95% confidence interval: 1.45-24.22). Conclusions: The hospital-based smoking cessation intervention might be effective for smoking cessation in patients with cerebral infarction, especially when the intervention was implemented thoroughly.

Soft rot occurred severely in onion bulbs stored under low temperature ($5^{\circ}C$) in storage houses at Changyoung, Kyungnam province, Korea in early 2000. Water-soaking and yellowish-brown lesions initially appeared on the outside scales of diseased onion bulbs, gradually progressing into the inside scales. Among the bacterial isolates obtained from the lesions, K-2 isolate was found to be responsible for the disease, which grew at a temperature range of from $0^{\circ}C$ to $36^{\circ}C$ with optimum temperature of $00^{\circ}$-$33^{\circ}C$. However, it showed strong pathogenicity to onion bulbs at $25^{\circ}C$ and $5^{\circ}C$ at 3 days and 2 months, respectively. The bacterium also caused soft rot on potato and showed hypersensitive reactions to tobacco and potato. The causal bacterium of onion soft rot was identified as Pseudomonas marginalis based on morphological, biochemical, and physiological characteristics including LOPAT, Soft rot in onion under low temperature storage caused by P. marginalis has not been previously reported.
Purpose: This review examined literature relevant to adolescent's health behavior in order to identify key behaviors and factors related to health behaviors for targeting health promotion interventions. Method: A critical review of 29 research articles was carried out using the guidelines suggested by Cooper. Result: The majority of the studies were descriptive and cross-sectional. Generally. the study includes sub-dimensions such as general hygiene and daily life habit, safety and accident prevention, nutrition and eating (tobacco, drinking), exercise, mental health and stress management, health duty (drug, health examination, disease prevention). Factors highly related to health behaviors were age, living areas, economic status, parent health behaviors, parent health concern, social support, friends influence, self-efficacy, self-esteem, locus of control, and the perceived health status. Sex, parent education and health knowledge were not related to health behaviors of adolescents. Conclusion: Several conceptual and methodological problems were identified in the studies review, such as restricted conceptualization of health behaviors and sampling issues which limit the generalizability of the study outcomes. Further research is needed to enhance the concept clarification and generalizablity of the study results.
