Abstract

BackgroundEndotoxin (lipopolysaccharide) is a widespread contaminant in many environmental settings. Since the 1970s, there has been generally consistent evidence indicating reduced risks for lung cancer associated with occupational endotoxin exposure.MethodsWe updated a case-cohort study nested within a cohort of 267,400 female textile workers in Shanghai, China. We compared exposure histories of 1456 incident lung cancers cases diagnosed during 1989-2006 with those of a reference subcohort of 3022 workers who were free of lung cancer at the end of follow-up. We applied Cox proportional hazards modelling to estimate exposure-response trends, adjusted for age and smoking, for cumulative exposures lagged by 0, 10, and 20 years, and separately for time windows of ⩽15 and >15 years since first exposure.ResultsWe observed no associations between cumulative exposure and lung cancer, irrespective of lag interval. In contrast, analyses by exposure time windows revealed modestly elevated, but not statistically significant relative risks (∼1.27) at the highest three exposure quintiles for exposures that occurred >15 years since first exposure.ConclusionsThe findings do not support a protective effect of endotoxin, but are suggestive of possible lung cancer promotion with increasing time since first exposure.

Abstract

Recent fossil discoveries from New Zealand have revealed a remarkably diverse assemblage of Paleocene stem group penguins. Here, we add to this growing record by describing nine new penguin specimens from the late Paleocene (upper Teurian local stage; 55.5–59.5 Ma) Moeraki Formation of the South Island, New Zealand. The largest specimen is assigned to a new species, Kumimanu fordycei n. sp., which may have been the largest penguin ever to have lived. Allometric regressions based on humerus length and humerus proximal width of extant penguins yield mean estimates of a live body mass in the range of 148.0 kg (95% CI: 132.5 kg–165.3 kg) and 159.7 kg (95% CI: 142.6 kg–178.8 kg), respectively, for Kumimanu fordycei. A second new species, Petradyptes stonehousei n. gen. n. sp., is represented by five specimens and was slightly larger than the extant emperor penguin Aptenodytes forsteri. Two small humeri represent an additional smaller unnamed penguin species. Parsimony and Bayesian phylogenetic analyses recover Kumimanu and Petradyptes crownward of the early Paleocene mainland NZ taxa Waimanu and Muriwaimanu, but stemward of the Chatham Island taxon Kupoupou. These analyses differ, however, in the placement of these two taxa relative to Sequiwaimanu, Crossvallia, and Kaiika. The massive size and placement of Kumimanu fordycei close to the root of the penguin tree provide additional support for a scenario in which penguins reached the upper limit of sphenisciform body size very early in their evolutionary history, while still retaining numerous plesiomorphic features of the flipper.

Abstract

One of the key problems in designing and implementing graph analysis algorithms for distributed platforms is to find an optimal way of managing communication flows in the massively parallel processing network. Message‐passing and global synchronization are powerful abstractions in this regard, especially when used in combination. This paper studies the use of a hardware‐implemented refutable global barrier as a design optimization technique aimed at unifying these abstractions at the API level. The paper explores the trade‐offs between the related overheads and performance factors on a message‐passing prototype machine with 49,152 RISC‐V threads distributed over 48 FPGAs (called the Partially Ordered Event‐Triggered Systems platform). Our experiments show that some graph applications favour synchronized communication, but the effect is hard to predict in general because of the interplay between multiple hardware and software factors. A classifier model is therefore proposed and implemented to perform such a prediction based on the application graph topology parameters: graph diameter, degree of connectivity, and reconvergence metric. The presented experimental results demonstrate that the correct choice of communication mode, granted by the new model‐driven approach, helps to achieve 3.22 times faster computation time on average compared to the baseline platform operation.

Abstract

BACKGROUND: Smoking has been linked to mucinous ovarian cancer, but its effects on other ovarian cancer subtypes and on overall ovarian cancer risk are unclear, and the findings from most studies with relevant data are unpublished. To assess these associations, we review the published and unpublished evidence. METHODS: Eligible epidemiological studies were identified by electronic searches, review articles, and discussions with colleagues. Individual participant data for 28,114 women with and 94,942 without ovarian cancer from 51 epidemiological studies were analysed centrally, yielding adjusted relative risks (RRs) of ovarian cancer in smokers compared with never smokers. FINDINGS: After exclusion of studies with hospital controls, in which smoking could have affected recruitment, overall ovarian cancer incidence was only slightly increased in current smokers compared with women who had never smoked (RR 1·06, 95% CI 1·01-1·11, p=0·01). Of 17,641 epithelial cancers with specified histology, 2314 (13%) were mucinous, 2360 (13%) endometrioid, 969 (5%) clear-cell, and 9086 (52%) serous. Smoking-related risks varied substantially across these subtypes (p(heterogeneity)

Abstract

Modern heterogeneous devices contain tightly coupled CPU and FPGA logic, allowing low latency access to accelerators. However, designers of the system need to treat accelerated functions specially, with device specific code for instantiating, configuring, and executing accelerators. We present a system level linker, which allows functions in hardware and software to be linked together to create heterogeneous systems. The linker works with post-compilation and post-synthesis components, allowing the designer to transparently move functions between devices simply by linking in either hardware or software object files. The linker places no special emphasis on the software, allowing computation to be initiated from within hardware, with function calls to software to provide services such as file access. A strong type-system ensures that individual code artifacts can be written using the conventions of that domain (C, HLS, VHDL), while allowing direct and transparent linking.

Abstract

Background Menarche and menopause mark the onset and cessation, respectively, of ovarian activity associated with reproduction, and affect breast cancer risk. Our aim was to assess the strengths of their effects and determine whether they depend on characteristics of the tumours or the affected women.Methods Individual data from 117 epidemiological studies, including 118 964 women with invasive breast cancer and 306 091 without the disease, none of whom had used menopausal hormone therapy, were included in the analyses. We calculated adjusted relative risks (RRs) associated with menarche and menopause for breast cancer overall, and by tumour histology and by oestrogen receptor expression.Findings Breast cancer risk increased by a factor of 1.050 (95% CI 1.044-1.057; p < 0.0001) for every year younger at menarche, and independently by a smaller amount (1.029, 1.025-1.032; p < 0.0001), for every year older at menopause. Premenopausal women had a greater risk of breast cancer than postmenopausal women of an identical age (RR at age 45-54 years 1.43, 1.33-1.52, p < 0.001). All three of these associations were attenuated by increasing adiposity among postmenopausal women, but did not vary materially by women's year of birth, ethnic origin, childbearing history, smoking, alcohol consumption, or hormonal contraceptive use. All three associations were stronger for lobular than for ductal tumours (p < 0.006 for each comparison). The effect of menopause in women of an identical age and trends by age at menopause were stronger for oestrogen receptor-positive disease than for oestrogen receptor-negative disease (p < 0.01 for both comparisons).Interpretation The effects of menarche and menopause on breast cancer risk might not be acting merely by lengthening women's total number of reproductive years. Endogenous ovarian hormones are more relevant for oestrogen receptor-positive disease than for oestrogen receptor-negative disease and for lobular than for ductal tumours.Funding Cancer Research UK.

Abstract

Los contraceptivos orales protegen frente al cancer epitelial ovarico y el cancer de endometrio. El grado de proteccion frente a ambos tipos de cancer aumenta con la duracion de su uso y persiste durante mas de una decada tras la interrupcion del tratamiento. El carcinoma hepatocelular, es una consecuencia muy poco frecuente de la utilizacion de los contraceptivos orales en aquellos paises en los que las cifras de frecuencia de esta enfermedad son bajas, pero no se ha demostrado esta complicacion en las regiones donde la hepatitis C es endemica y las tasas subyacentes son elevadas. El riesgo de los adenomas celulares hepaticos tambien es mayor entre las usuarias de los contraceptivos orales. El colangiocarcinoma y el carcinoma de la vesicula biliar no se han asociado con la utilizacion de los contraceptivos orales. Se ha observado de modo bastante preciso que a mayor duracion del empleo de los contraceptivos orales tambien es mayor el riesgo de aparicion de un carcinoma cervical de celulas escamosas, tantoin situ como invasivo, incluso despues de eliminar los posibles efectos confusivos de los examenes citologicos y el comportamiento sexual de las mujeres estudiadas y sus parejas. El riesgo del adenocarcinoma cervical tambien se ha asociado con el uso de los contraceptivos orales. El empleo de estos preparados no se ha relacionado con una alteracion global del riesgo de cancer de mama en los estudios en los que se incluyeron mujeres con una amplia variacion de edades. Sin embargo, su utilizacion a largo plazo se ha asociado con un aumento del riesgo del cancer de mama en mujeres de menos de 45 anos. El empleo de los contraceptivos orales no se ha relacionado con el riesgo de aparicion del melanoma maligno.

Abstract

Background The Collaborative Group on Hormonal Factors in Breast Cancer has brought together and reanalysed the worldwide epidemiological evidence on the relation between breast cancer risk and use of hormonal contraceptives. Methods Individual data on 53297 women with breast cancer and 100 239 women without breast cancer from 54 studies conducted in 25 countries were collected, checked, and analysed centrally. Estimates of the relative risk for breast cancer were obtained by a modification of the Mantel-Haenszel method. All analyses were stratified by study, age at diagnosis, parity, and, where appropriate, the age a woman was when her first child was born, and the age she was when her risk of conception ceased. Findings The results provide strong evidence for two main conclusions. First, while women are taking combined oral contraceptives and in the 10 years after stopping there is a small increase in the relative risk of having breast cancer diagnosed (relative risk [95% CI] in current users 1.24 [1.15-1.33], 2p

Abstract

The Collaborative Group on Hormonal Factors in Breast Cancer has brought together and reanalysed the worldwide epidemiological evidence on breast cancer risk and use oi hormonal contraceptives. Original data from 54 studies, representing about 90% of the information available on the topic, were collected, checked and analysed centrally. The 54 studies were performed in 26 countries and include a total of 53,297 women with breast cancer and 100,239 women without breast cancer. The studies were varied in their design, setting and timing. Most information came from case-control studies with controls chosen from the general population; most women resided in Europe or North America and most cancers were diagnosed during the 1980s. Overall 41% of the women with breast cancer and 40% of the women without breast cancer had used oral contraceptives at some time: the median age at first use was 26 years, the median duration of use was 3 years, the median year of first use was 1968, the median time since first use was 16 years, and the median time since last use was 9 years. The main findings, summarised elsewhere,I are that there is a small increase in the risk of having breast cancer diagnosed in current users of combined oral contraceptives and in women who had stopped use in the past 10 years but that there is no evidence of an increase in the risk more than 10 years after stopping use. In addition, the cancers diagnosed in women who had used oral contraceptives tended to be less advanced clinically than the cancers diagnosed in women who had not used them. Despite the large number of possibilities investigated, few factors appeared to modify the main findings either in recent or in past users. For recent users who began use before age 20 the relative risks are higher than for recent users who began at older ages. For women whose use of oral contraceptives ceased more than 10 years before there was some suggestion of a reduction in breast cancer risk in certain subgroups, with a deficit of tumors that had spread beyond the breast, especially among women who had used preparations containing the highest doses of oestrogen and progestogen. These findings are unexpected and need to be confirmed. Although these data represent most of the epidemiologi cal evidence on the topic to date, there is still insufficient information to comment reliably about the effects of specific types of oestrogen or of progestogen. What evidence there is suggests, however, no major differences in the effects for specific types of oestrogen or of progestogen and that the pattern of risk associated with use of hormonal contraceptives containing progestogens alone may be similar to that observed for preparations containing both oestrogens and progestogens. On the basis of these results, there is little difference between women who have and have not used combined oral contraceptives in terms of the estimated cumulative number of breast cancers diagnosed during the period from starting use up to 20 rears after stopping. The cancers diagnosed in women who have used oral contraceptives are, however, less advanced clinically than the cancers diag nosed in never users. Further research is needed to establish whether the associations described here are due to earlier diagnosis of breast cancer in women who have used oral contraceptives, to the biological effects of the hormonal contraceptives or to a combination of both. Little information is as yet available about the effects on breast cancer risk of oral contraceptive use that ceased more than 20 years before and as such data accumulate it will be necessary to reexamine the worldwide evidence.

Abstract

Alcohol and tobacco consumption are closely correlated and published results on their association with breast cancer have not always allowed adequately for confounding between these exposures. Over 80% of the relevant information worldwide on alcohol and tobacco consumption and breast cancer were collated, checked and analysed centrally. Analyses included 58515 women with invasive breast cancer and 95067 controls from 53 studies. Relative risks of breast cancer were estimated, after stratifying by study, age, parity and, where appropriate, women’s age when their first child was born and consumption of alcohol and tobacco. The average consumption of alcohol reported by controls from developed countries was 6.0 g per day, i.e. about half a unit/drink of alcohol per day, and was greater in ever-smokers than never-smokers, (8.4 g per day and 5.0 g per day, respectively). Compared with women who reported drinking no alcohol, the relative risk of breast cancer was 1.32 (1.19 - 1.45, P < 0.00001) for an intake of 35 - 44 g per day alcohol, and 1.46 (1.33 - 1.61, P < 0.00001) for greater than or equal to 45 g per day alcohol. The relative risk of breast cancer increased by 7.1% (95% CI 5.5-8.7%; P

Abstract

The Breast Health Global Initiative (BHGI) brought together international breast cancer experts to discuss breast cancer in low resource countries (LRCs) and identify common concerns reviewed in this consensus statement. There continues to be a lack of public and health care professionals' awareness of the importance of early detection of breast cancer. Mastectomy continues to be the most common treatment for breast cancer; and a lack of surgeons and anesthesia services was identified as a contributing factor in delayed surgical therapy in LRCs. Where available, radiation therapy is still more likely to be used for palliation rather than for curative treatment. Tumor receptor status is often suboptimally performed due to lack of advanced pathology services and variable quality control of tissue handling and processing. Regional pathology services can be a cost-effective approach and can serve as reference, training and research centers. Limited availability of medical oncologists in LRCs often results in non-specialist providing chemotherapeutic services, which requires additional supervision and training. Palliative care is an emerging field in LRCs that requires investment in training and infrastructure development. A commitment and investment in the development of breast cancer care services by LRC governments and health authorities remains a critical need in LRCs.

Abstract

Objective : To investigate a high incidence of congenital malformations, morbidity and mortality in infants of drug abusing mothers. Methodology : In a 10 and a half year period from 1984–95, 497 such babies were reviewed whose mothers had abused a variety of drugs. Results : Thirty babies died or had serious disability. There were five cases of SIDS and 19 babies had major malformations, including seven with cleft lip/palate. Six babies had significant gastrointestinal disorders or feeding difficulties. Conclusion : The incidence of clefting was 10 times the normal rate and SIDS five times the expected incidence. In a group of mainly socially disadvantaged women, the abuse of narcotics, amphetamines and other substances, with possible sub-optimal nutrition, may have been contributory to this high morbidity and mortality. No specific drug could be implicated.

Abstract

The purpose of this study was to observe the effects of methadone exposure in utero, with special reference to maternal and neonatal methadone concentrations and neonatal withdrawal. Two groups of mother-infant pairs were studied. In the first group, serum methadone concentrations were determined in infants at 1, 6 and 24 h after delivery. In the second group, blood was obtained at 24, 48, 72 and 96 h after birth. There was no correlation between neonatal serum levels and the intensity of withdrawal symptoms. There was no relationship between maternal methadone dose at delivery or maternal serum levels and neonatal methadone levels. The results of this study may be complicated by the prenatal exposure of the neonates to other drugs of abuse apart from methadone.

Abstract

Background: Despite the fact that wound irrigation is a common surgical procedure, there are many variables, including delivery device, irrigant type, and fluid volume, that have yet to be optimized. The purpose of this study was to compare, with use of transgenic bioluminescent bacteria and standard quantitative microbiological methods, the efficacy of pulsed lavage and bulb syringe irrigation in reducing wound bacterial counts.Methods: A caprine model of a complex, contaminated musculoskeletal wound was developed with use of a bioluminescent strain of Pseudomonas aeruginosa that can be quantified. Luminescent activity was recorded as relative luminescent units with use of a photon-counting camera six hours after the wound was created and inoculated. Twelve goats were randomly assigned to either the pulsed lavage group or the bulb syringe irrigation group. Each wound was irrigated with normal saline solution in 3-L increments for a total of 9 L and was imaged after each 3-L increment. In addition, quantitative culture samples were obtained from different tissues within the wound before and after irrigation.Results: Pulsed lavage decreased the amount of relative luminescent units by 52%, 64%, and 70% at 3, 6, and 9 L, respectively. The bulb syringe irrigation reduced the amount of relative luminescent units by 33%, 44%, and 51% at these same time-points. Significant differences in luminescence were noted between the two groups after both 6 and 9 L of irrigation (p < or = 0.04). The correlation coefficients between relative luminescent units and quantitative cultures for the condition before irrigation and after irrigation were r = 0.96 and 0.83, respectively.Conclusions: Pulsed lavage was more effective than bulb syringe irrigation in reducing bacterial luminescence after both 6 and 9 L of irrigation. Both device and volume effects can be demonstrated with use of this model. Bioluminescent bacteria provide a method to visualize bacterial distribution and to quantify the bacteria in a wound.Clinical Relevance: Pulsed lavage is a more effective and efficient method of irrigation to remove bacteria in a complex musculoskeletal wound. In the model we used, pulsed lavage irrigation with 3 L of saline solution resulted in a reduction of approximately the same amount of bacteria as did irrigation with 9 L with use of a bulb syringe.

Abstract

This study was conducted to identify reproductive and dietary factors associated with benign proliferative mammary epithelial cell changes. Subjects were women enrolled in a randomized trial of breast self-examination in Shanghai, China. Women who developed fibrocystic breast conditions classified as nonproliferative (175 women), proliferative (181 women), or proliferative with atypia (33 women) between 1995 and 2000 and 1,070 unaffected trial participants were administered general risk factor and food frequency questionnaires. Conditional logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals. High parity and consumption of fresh fruits and vegetables were more strongly associated with a reduced risk of proliferative and atypical lesions than with nonproliferative conditions. For the fourth quartile of consumption versus the first, odds ratios for lesions diagnosed as nonproliferative, proliferative, and proliferative with atypia were 0.4 (95% confidence interval (CI): 0.2, 0.7), 0.2 (95% CI: 0.1, 0.4), and 0.1 (95% CI: 0.03, 0.5), respectively, for fruit intake and 0.6 (95% CI: 0.3, 1.1), 0.4 (95% CI: 0.2, 0.7), and 0.1 (95% CI: 0.1, 0.9), respectively, for vegetable intake. Reduced but nonsignificant risks in relation to soy products were observed for proliferative and atypical lesions. No single nutrient or botanical family was appreciably more strongly associated with proliferative conditions than with nonproliferative conditions, after results were controlled for total fruit and vegetable consumption. A diet rich in fruits and vegetables may reduce cellular proliferation in the mammary epithelium; this is one mechanism by which such a diet could reduce risk of breast cancer.

Abstract

Objective: The food-frequency questionnaire (FFQ) can be an efficient tool to evaluate dietary intake in large, population-based studies, especially for specific foods. The objective of this study was to validate the assessment of soy and isoflavone (daidzein and genistein) intakes, measured by an FFQ, by comparing intakes with serum isoflavone concentrations.Design and Setting: Soy and isoflavone intakes and serum isoflavone concentrations were determined as part of a case-control study of dietary factors and risks of benign breast disease and breast cancer. The FFQ, administered during an in-person interview, included six soy-specific line items. Blood was drawn within one week of FFQ completion.Subjects: In total, 1823 women living in Shanghai, People's Republic of China.Results: In this population, soybean milk, fresh bean curd and other bean foods were eaten once per week, and fermented bean curd, fried bean curd puff and soybeans were eaten less than once per week. A significant linear trend (P<0.01) in serum isoflavone concentrations across increasing categories of soy and isoflavone intakes was observed, indicating that soy and isoflavone intakes, measured by the FFQ, well distinguished serum isoflavone concentrations. Linear trends were also observed in both case and control groups in stratified analyses, suggesting little differential bias by case-control status.Conclusions: The results suggest that the FFQ provides a useful marker of soy food consumption and isoflavone exposure in this population.

36. Tubal sterilization and use of an IUD and risk of cervical cancer.

Author

Li H, Thomas DB, Jin S, and Wu F

Abstract

The relationship of tubal sterilization and use of an intrauterine device (IUD) to the risk of invasive squamous cell cervical cancer was evaluated in a case-control study carried out in Shandong, China, from 1989 to 1991. Patients (cases) were 272 women aged 30-77 years with newly diagnosed invasive squamous cell cervical cancer in Shandong Province Tumor Hospital. Controls were 893 randomly selected screened women matched to the cases by age (within 2 years) and county. A decrease in risk was observed in uses of an IUD, especially in long-term users under age 33. A nonsignificant decrease in risk in women under age 33 who had had a tubal ligation was also observed, especially in the first 10 years since the procedure. Tubal ligation and IUD insertion and removal provide opportunities to screen women for cervical cancer and reduce the risk of invasive disease. [ABSTRACT FROM AUTHOR]

Abstract

Background: Although depot medroxyprogesterone acetate (DMPA) (Depo-Provera) has now been approved for marketing as a contraceptive in the United States, there are still unresolved issues about the relation between DMPA and risk of breast cancer. The two substantial case-control studies of this association yielded similar but inconclusive results. Because their designs were compatible, these studies were pooled to obtain more adequate data for analysis.Design: Pooled results from two case-control studies.Setting: New Zealand (entire country), Thailand (three centers), Mexico (one center), and Kenya (one center).Participants: A total of 1768 women with breast cancer and 13,905 controls, most of whom were younger than 55 years.Main Outcome Measure: Relative risk (RR) of breast cancer in women who had used DMPA.Results: The RR of breast cancer for women who had ever used DMPA was 1.1 (95% confidence interval [CI], 0.97 to 1.4). There was no increase in risk with increasing duration of use of DMPA, but RR estimates were higher in certain subgroups of women. Further analyses suggested that recent (or current) use was the key factor, with women who had started using DMPA within the previous 5 years estimated to have an RR of 2.0 (95% CI, 1.5 to 2.8).Conclusions: The increased risk of breast cancer observed in recent (or current) users could be due to enhanced detection of breast tumors in women using DMPA or to acceleration of the growth of preexisting tumors. Women who had used DMPA more than 5 years previously had no increase in risk of breast cancer, regardless of their duration of use. [ABSTRACT FROM AUTHOR]

Abstract

Serial investigations of electrolytes, osmolality and nutritional status were undertaken in 28 babies less than 33 weeks gestation. 6 died with intraventricular haemorrhage, 9 died without intraventricular haemorrhage, and 13 survived. Significant hypersomality was detected in the babies who died with intraventricular haemorrhage, whereas babies who died without intraventricular haemorrhage and survivors had values within normal limits. No relation was found between hyperosmolality and sodium concentrations. Total fluid intake and caloric intake were comparable in the three groups, but protein intake was much reduced in babies with intraventricular haemorrhage due to a lower milk intake. The hyperosmolality could have resulted from tissue breakdown following protein starvation and may be a factor in the occurrence of intraventricular haemorrhage. In premature babies an osmolality of over 320 mOsm/l carried a grave prognostic implication.

Abstract

Data from nine population-based cancer registries participating in the Surveillance, Epidemiology, and End Results Program (1973-1982) were analyzed to determine whether the incidence of different histologic types of respiratory tract cancers varies by anatomic location. The variation in cancer incidence among respiratory tract subsites was remarkable for squamous cell carcinoma, but the variation was less prominent for adenocarcinoma. The rates of squamous cell carcinoma and adenocarcinoma along the airways correspond closely with the deposition pattern of large and small smoke particles, respectively. Also, the rates of adenocarcinoma parallel the distribution of surface glandular cells of the respiratory tract. Our results support the hypothesis that anatomy and physiology, in conjunction with size of particles in inhaled cigarette smoke, play an important role in the genesis of specific histologic types of respiratory tract cancers.

Abstract

The formation of zones of iron con centration in the spleen of the mouse radiation chimera is inhibited by transfusion-induced polycythaemia. This is consistent with the view that these zones represent colonies which contain aρ-preciable numbers of erythroblasts. On the surface of the spleen, such colonies outnumber colonies which do not accumulate iron by more than 4 to 1.

Abstract

The rate of cell production of a mammary adenocarcinoma following surgical biopsy has been investigated using vincristine sulphate as a metaphase arrest agent. Small implants of the tumour were implanted into the inguinal region of young mice of both sexes and were seen to have a constant rate of cell production both between different tumour generations and during tumour growth. Such a constant rate of tumour cell production provides an extremely useful model for exploring the effects of surgical biopsy. Measurements of the cell production rate showed a 60 per cent decrease for the first 48 hours following biopsy after which recovery ensued to reach control levels again. Sham-anaesthetized controls and sham-resected controls demonstrated none of these changes. Similar depression in the rate of cell production was seen following biopsy of one tumour in mice bearing bilateral tumours. The 48-hour depression was observed both in the ipsilateral remnant tumour and in the contralateral implant which has not been biopsied.
